    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020. She cared a lot about the boys and worked hard to create meaningful activities for them. The pod experience was invaluable … More for all of our families during a difficult year and we were so grateful to have found this partnership! We also want to appreciate Craig for helping to match us with a tutor on very short notice after we had cycled through a few folks who were not able to see the commitment through. Thanks for sticking with us!

    Dusty was the exact person we needed to help our child finish out the school year. So grateful to him for the way he steadily encouraged her and helped her stay on track and organized. He is flexible, responsive to our needs/schedule as … More a family, and a delight to be with. We are also thankful that Craig at Themba Tutors really "gets it" and partnered us with such a wonderful tutor who was a great fit for our girl.
  • Avatar Nicole May ★★★★★ 11 months ago
    My child worked with Gillian D virtually for math enrichment. She is an excellent teacher. She took time to understand my child's specific learning style and provided tools that would be engaging. She was kind and empathetic- really … More made it her goal to connect with my child and build trust and rapport. My child started the school year with confidence and without the typically "brain-drain" that occurs over the summer, thanks to Gillian.

    I am going into my second year as a Themba tutor. I have met so many great individuals while working for this company. Craig and the rest of the Themba team do such an excellent job picking and choosing Themba tutors that suit each client's … More individual needs! I look forward to meeting new tutors and clients in the 2021-2022 school year!
  • Avatar carolina luttmann ★★★★★ 11 months ago
    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics. I found Themba Tudors online and had an initial call with Craig, who was very knowledgeable, responsive, and found 2 amazing tutors for … More us. Both the Latin and the physics tutors were fantastic, connected with my son really well and helped him go from 'failing' grade to 'honors'! I will for sure continue using (and recommending!) Themba Tutors. Thank you, C, K, and W!

    Brian is a fantastic executive functioning coach. Super helpful, flexible with hours, and tailored the experience to our needs.
  • Avatar Susan Wong ★★★★★ a year ago
    Giulia Mercuri is a great Italian tutor! She was very responsive and accessible. Giulia put a ton of effort into preparing for each session and really helped our son with test preparation and projects. We are grateful that she was able … More to help, especially since our son did not receive any live teaching during COVID. We are happy that she was referred to us!
  • Avatar Christine Gennetti ★★★★★ a year ago
    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.
    I can wholeheartedly say after working with Themba for two years that I would not have finished my program without this organization. And I am so thankful I selected them.
  • Avatar Fabiola FITZPATRICK ★★★★★ 2 years ago
    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved. The tutor taught our son subject content and various methods to effectively … More study for quizzes and exams. Our son was also taught time management and organization. My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ a year ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    Victoria is a superb tutor. She helped my high school age daughter with her writing. Victoria's skills as a tutor, as well as her sense of humor and her engaging personality went a long way with my daughter.

    I'm so glad we were referred to Themba Tutors. After a great initial conversation to learn our needs, we were connected with an excellent tutor, Felicia, who is helping our high school daughter learn better organizational and executive … More skills. Highly recommended.
  • Avatar Fara Jones ★★★★★ 3 years ago
    Themba Tutors provided a leaning specialist that was a perfect fit for my daughter. I told them what we were looking for and they delivered. Our tutor is responsive and flexible and makes it easy for my daughter to reach out to her own … More her own, which gives her an added sense of responsibility over her learning. As a therapist myself, I now regularly recommend Themba to my patients. A much needed and well provided service to the community!!
  • Avatar Frances Simpson ★★★★★ 3 years ago
    The tutors at Themba are fantastic! Caitlyn McNeill helped our son academically, but also with getting organized in every subject, which he so desperately needed. She offered great advice and useful strategies that helped our son become … More a more successful student. We are using Themba tutors again this year for our daughter. We're so happy to have been referred to them!

    Paul Smith at Themba has been an exceptional tutor for my son, both in terms of teaching the subject matter and teaching how best to approach the process of learning math and executing assignments. We feel very fortunate to be working with … More Paul.

    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write. Edwouine just works her magic with him, he adores her and is so … More eager to follow her guidance. I have no doubt she will be a positive driving force in his academic future.

What Is a Test Prep?

We offer  SAT, GRE, SHSAT, ISEE/SSAT, ELA, Regents, TASC, MAP Growth, LOTE, and GED test prep tutoring services. Scroll down below for more info about these exams.


In test preparation, a one-size-fits-all approach tends to be ineffective. Tutoring is most powerful when customized to your child’s unique learning profile. Themba Tutors teach test content but, more importantly, help build underlying skills. Most of our students have formally recognized learning issues for which special accommodations are granted, such as extended time or multiple-day testing. The test-taking strategies we teach incorporate such accommodations to the benefit of the student.


What to do before exams? Good Study Habits


Keep Up with Your Work


If you attend class regularly, continue with readings, and take notes conscientiously, studying is often a comparatively pain-free process. Make sure to expand and review class notes regularly throughout the semester. It would be best if you considered making a glossary or collection of note cards for vocabulary review in each class. Many students find that preparing for a private class for 60-90 minutes per day, five or six days per week, will leave them well-prepared at exam time. To assist students with the organization at finals time, we have compiled a couple of time management tools included with this page.


Don’t Cram at the Last Second


Building off our previous entry, try studying for 60-90 minutes per day for every week leading up to an exam. All-nighters don’t work for most people, and students experience declining returns on their efforts when they attempt to study for four and five hours straight.

What Are the Things to Do Before an Exam?

Complete a Mock Test


Many social science, natural science, and foreign language textbooks contain hundreds of questions at the end of chapters that are never answered. You should set aside an hour and try to answer these questions on a paper without using your notes? If you can complete a mock test 3-5 days before an exam, you’ll then know where to focus your studying. You may also combat pre-test jitters by demonstrating to yourself what you recognize. Try answering a few potential essay questions on a timed, mystery basis, and see how you are doing. Other simple tips in conducting a mock test are to ask a friend or classmate or your parents to offer you an oral quiz supported concepts within the textbook or in either of your notes.


Do Not Multitask While Studying


Set aside time to review beforehand then follow through. For most people, meaning leaving your dormitory and turning off visual/auditory distractions, including iPods, Facebook, and music with lyrics. If you’ve got outstanding questions, see your professor or tutor a minimum of three days before the exam. If you’ve given yourself a mock test beforehand, you’ll be ready to attend office hours with an agenda.


Think about what written questions could be on the exam; Outline each potential essay as a pretesting and practice.


Find a Group of Dedicated Students with Whom to Review


A group study session is a perfect time to review and compare notes, ask one another questions, explain ideas to at least one another, discuss the upcoming exam and difficult concepts, and, when appropriate, delegate study tasks. Do set an agenda and a selected time-frame for your group study session so that your work together doesn’t veer off-topic.


Listen for Clues From Your Teachers


Your teacher or your professor will sometimes come right out and tell you about the exam or help you plan your studying strategies. You need to be in school a day to receive such help. Use review sheets thoroughly.


Review your class notes every day. You can add hints, keywords, summaries, idea maps, graphs, charts, discussion points, and questions where applicable. Take the time to arrange lecture notes after class, adding key examples from labs and course readings.





The SAT is an entrance exam used by most colleges and universities to make admissions decisions. The SAT is a multiple-choice, pencil-and-paper test created and administered by the College Board. 


The SAT’s purpose is to measure a high school student’s readiness for college and provide colleges with one common data point that can be used to compare all applicants. Here are some essential college readiness guidelines and skills to follow.



The Graduate Record Examination, or GRE, is an important step in the graduate school or business school application process. The GRE is a multiple-choice, computer-based, standardized exam often required for admission to graduate programs and graduate business programs (MBA) globally.


The GRE measures your command of basic arithmetic, algebra, geometry, and data analysis, as well as college-level vocabulary. More importantly, it measures your ability to analyze and evaluate written material, think critically, and solve problems.




The Specialized High School Admissions Test (SHSAT) is the only criterion for admissions to 8 of the 9 New York City Specialized High Schools. The only exception is the Fiorello H. LaGuardia High School of Music & Art and Performing Arts, which requires an audition or portfolio for admission.


The SHSAT is administered by the New York City Department of Education and is only available to New York City residents in the 8th grade. 9th-grade students may also choose to take the 9th-grade version of the SHSAT for a very limited number of seats that may become available at the Specialized High Schools.




The Secondary School Aptitude Test (SSAT) and the Independent School Entrance Exam (ISEE) is the two admissions tests used to determine placement into independent and private junior highs and high schools.




The ELA test is an untimed test that contains several different kinds of questions. Students answer multiple-choice questions based on short passages they read and write responses to open-ended questions based on stories, articles, or poems they listen to or read.


New York State Regents


Regents exams measure student achievement in high school-level courses. To graduate from high school in New York State, students must pass five Regents exams in the following subject areas: English Language Arts, math, a science, social studies/history, and any additional Regents exam or another option approved by the State. Read this article to learn more about NY REGENTS- Standardized Test Prep.



TASC Test Assessing Secondary Completion™ is a state-of-the-art and affordable national high school equivalency assessment. It assesses five subject areas, including Reading, Writing, Mathematics, Science, and Social Studies. The TASC Test measures examinees’ levels of achievement relative to graduating high school seniors, as outlined by the College and Career Readiness standards. Here are 7 basic life skills to learn for college readiness.


MAP Growth


MAP Growth is a computerized adaptive test that helps teachers, parents, and administrators improve learning for all students and make informed decisions to promote a child’s academic growth. It is a comprehensive assessment that focuses on tracking the growth of students in grades K-12 through the school year. Though the test is untimed, each subject takes approximately 45 minutes to complete. The computer-adaptive assessment is aligned with the Common Core State Standards and Next Generation Science Standards. MAP GROWTH is part of the MAP Suite, which also contains MAP Skills.




The LOTE Comprehensive exam assesses students’ proficiency at Checkpoint B of the NY State Education Department’s learning standards for Languages Other Than English.


On the LOTE Comprehensive exam, students are required to:

  • Have conversations in the language being tested
  • Listen to the test administrator speak in the language being tested and answer multiple-choice questions
  • Read a text in the language being tested (for example, a menu or poem) and answer multiple-choice questions
  • Write two essays in the language being tested.




Since GED is an alternative to a high school diploma. It is highly recommended that you prepare for it. You will receive a test score vouching for your high school knowledge equivalency and college readiness. Obtaining Your GED offers better chances of furthering your education. Here is the ultimate guide for college readiness. Take advantage of this College Readiness – Preparation For The Future: A Senior Boot Camp to access various skills to learn and improve upon them.




Take Notes on the Course Readings


You should also review these notes daily. Again, create visual enhancements when possible (e.g., compare/contrast charts, timelines, etc.). Use both your course notebook and, therefore, the text’s margins to record valuable information. Please see our entries on reading for further information on this topic.


Make Sure to Get Plenty of Sleep


Sleeping hours are often the time once we completely synthesize information, especially topics we’ve covered a few hours before bedtime. You want to be as fresh as possible and ready to engage your memory once you take the exam fully. Also, don’t stop exercising or taking time for yourself, even at the final exam time.

Find Ways to Apply Materials from Class


Think about how exams subject and topics are related to your personal interests, societal problems, and controversies, issues raised in other classes, or different experiences in your life.

How long does it take on average to get ready for the SHSAT and ISEE tests?
The most successful students take up to 4-6 months of weekly sessions, Summertime sessions double up to address both ELA and Math advanced topics before school starts: this helps the student build stamina to sit through long passages and develop key test taking strategies that are centered around how the child learns best. The toughest topics are taught in the summer.
Can you do one set of tutoring that meets the needs of both the SHSAT and ISEE tests - or do you need separate prep for each one?
They can be accomplished at the same time. ISEE requires more topics that have to be covered in Quantitative Reasoning and Verbal Reasoning and its usually taken at a later date than SHSAT ( two months apart).
What do you think of interview prep services for high school application interviews? Worth the money?
Yes, it helps the student build the confidence needed and the appropriate language and word choice/ vocabulary to use when responding to questions such as  1. Tell me a little bit about yourself, 2- Why do you think you’re a good candidate for this school? 3- What are some of your strengths/weaknesses 4- What is your best quality that makes you stand out from the rest  5- What is the last book you read and how can you apply some of the themes in the book to your real-life 6- Why do you want to come to this school? What can we offer you that another school can’t?  7- Can you tell me about a time when you felt that something didn’t go your way and how you responded to that situation?  8- Do you have any questions for me (which 100% the student should have 3 questions ready to ask the interviewer).
Most students that interview really well have already structured thoughtful and meaningful responses because they’re practiced a whole lot. Students that don’t do well freeze up, never answer the question, respond using colloquial language, and are patiently waiting for the interview to be over. It’s apparent to the interviewer if the student matches the individual presented on the application.

My son, a junior in a private high school worked, with a wonderful tutor from Themba to get ready for his SATs. I spoke with Blythe and she asked detailed questions about my sons strengths and weaknesses. She put me in touch with Don, who worked beautifully with my son. Don immediately understood where my son needed help and focused their time together on specific areas of need. He also recognized my sons strengths ( math )and was able to accelerate his understanding in those areas. My sons score jumped 190 points! The individualized instruction he got from Themba and Don was amazing! I highly recommend these wonderful people.

-Marie W.

Matt tutored my son for the SAT & ACT this fall We liked his positive approach to help learn the necessary testing skills. He is friendly, thoughtful and points out strengths while emphasizing areas that need extra work. Thank you for sending him to us!

-Colleen Donohue

Having been through the SAT/ACT tutoring process before with my older daughter, I knew we d need something less conventional, more tailor-made, for my son–someone who could adjust and meet the needs of my son s specific learning needs. My son has ADHD and easily becomes overwhelmed and anxious with regards to test-taking. After his first tutoring session with Dr. Brooke, we knew it was a “good fit . She was able to quickly develop a great working rapport with my son. She understood that he needed to be gently challenged, praised and continually encouraged to keep him from becoming overly frustrated. His original PSAT score was a 26. Dr. Brooke helped him to bring his ACT score up to a 31. We can’t thank her enough!

-Hilary V.

Alissa is an amazing professional and person! Our entire family loves and appreciates her. My son got considerably better at test-taking for the SHSAT. Thanks so much!
