Before and After Results
Real score improvements from students in our SAT, AP, ACT and GMAT programs.
Detailed Case Studies
In-depth stories from our students who achieved outstanding results.
I was devastated after my first SAT attempt. The diagnostic test identified my weak points in Reading and Math, and my tutor created a focused plan. In 4 months I went up 240 points and got accepted to UCLA!
After trying other programs, TestPrep Istanbul finally worked. The personalized approach to Data Sufficiency and Critical Reasoning made all the difference. Now I'm doing my MBA at Wharton.
The Science section was my biggest weakness. My tutor taught me efficient data interpretation strategies. The small group format kept my motivation high and I went from 24 to 34!

Separating calculation errors from content gaps made revision more useful. A big thank you to my tutor for all the support :)
Leonor Simoes
- LNAT
The LNAT format felt unnecessarily confusing at first. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. Discussing why the other choices were wrong helped more than I expected. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Nathan Vickers
- AP Exams
Even in a group lesson, the tutor knew where each of us stood. Over time, AP Calculus AB became one of the most organized parts of my AP Exams preparation. I became much more comfortable asking questions in class. I'm glad I worked with my tutor through this process.
Facundo Mercado
- Digital SAT
We focused more on understanding what the problem asked than memorizing formulas. Thanks to everyone who supported me.
Amandine Faure
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. Thank you to my tutor and the TestPrep team.
Priya Basu
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. We didn't spend extra time on things I already knew. We focused more on understanding what the problem asked than memorizing formulas. I never felt awkward asking the same thing again. My tutor could see my reasoning and usually found the source of an error quickly. The preparation felt calmer than I expected.
Thomas Baxter
- A-Level
The tutor supported regular study, not only the lesson content. We were pleased with the support we received.
Gael Masson
- ACT
We were realistic about what could be improved in the time available. The feedback I received on ACT Science was clear and practical. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)
Irene Gallardo
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I left the exam feeling that I had done what I could.
Marta Prieto
- IGCSE / GCSE
What annoyed me most was losing easy points because I rushed. After a while, the questions started to feel much more familiar.
Siddharth Menon
- ACT
When I started preparing for ACT, I wasn't sure what order to study things in. I'm glad I worked with my tutor through this process.
Felix Maes
- Digital SAT
I was taking Craft & Structure at school, but getting used to the exam questions took time. My mock results gradually became more consistent.
Marissa Reynolds
- AP Exams
Joining lessons willingly was one of the clearest signs for us. The plan was adjusted when school exams became busy. We were pleased with the support we received.
Anais Allard
- UCAT
When I started preparing for UCAT, I wasn't sure what order to study things in. It was an intense period, but it was worth it.
Henrik Horvat
- IMAT
Everyone recommended different resources and I kept switching between them. Thank you to my tutor and the TestPrep team.
Rasmus Prochazka
- IB Diploma
We noticed that the resources kept changing during independent study. The tutor's close attention to weaker areas gave us confidence. Seeing the change in our child made us very happy.
Nathan Teague
- GRE General
I finally understood what was going wrong in Sentence Equivalence. I stopped choosing answers by feel and started looking for evidence in the passage. My preparation became much more regular and easier to track.
Anders Mazur
- IGCSE / GCSE
After the first attempt, we looked for a calmer plan for the retake. Flexible scheduling helped during a demanding school year. The tutor's close attention to weaker areas gave us confidence. It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. We were pleased with the support we received.
Wenjing Xu
- PTE Academic
The feedback I received on Computer-Based Practice was clear and practical. Predicting the output helped me catch small logic errors. My preparation became much more regular and easier to track.
Rui Saez
- TOEFL iBT
Our child wasn't sure how to organize the preparation for TOEFL iBT. Online lessons made it possible to continue without losing time on travel. The lessons started being followed without constant reminders from us. The tutor's close attention to weaker areas gave us confidence. We were able to follow the mock results regularly. We were pleased with the support we received.
Elena Amato
- IB Diploma
I finally understood what was going wrong in IB English B. Discussing why the other choices were wrong helped more than I expected. Knowing what to study reduced a lot of the stress.
Felipe Cordero
- ACT
Breaking Time Management into smaller pieces worked much better for me. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress.
Preecha Kanjana
- SSAT
After the first attempt, we looked for a calmer plan for the retake. The plan was adjusted when school exams became busy.
Toby Whitlam
- PTE Academic
I had been studying alone, but my results stopped improving after a point. The group never had more than six students, so it was easy to stay involved. The writing feedback helped me stop repeating the same sentence-level errors. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. It was an intense period, but it was worth it.
