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!

The feedback I received on IGCSE Combined Science was clear and practical. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track.
Carmen Cabrera
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. The class felt relaxed enough to ask questions without overthinking it. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

We wanted our child to keep up with the school pace in IGCSE Biology. The tutor supported regular study, not only the lesson content. We thank the tutor and the TestPrep team.

Anouk Visser
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. The plan changed with my mock and homework results, so the work never felt random. I used the question bank regularly to return to weaker topics. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I left the exam feeling that I had done what I could. I was really happy with the lessons.
Owen Dalton

Viviana Acosta
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. After enough examples of the same question type, the repeated mistakes decreased. I became much more careful with graphs, experiments and data-based questions. My confidence improved along with the results. The preparation felt calmer than I expected.

A big thank you to my tutor for all the support :)
