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!

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Breaking Optional Writing into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. I learned not to spend the same amount of time on every line of a long text. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.

Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. The tutor's close attention to weaker areas gave us confidence. Mistakes became something to work on rather than something to feel bad about. Communication with the team was straightforward and our questions were answered. The overall experience was positive from beginning to end.
Claudia Tavares
- ACT
What annoyed me most was losing easy points because I rushed. Near the exam, it was clear what to keep doing and what to stop. A lot of my mistakes came from rushing through the wording of the question. A big thank you to my tutor for all the support :)

I was taking Time Management at school, but getting used to the exam questions took time. Even in a group lesson, the tutor knew where each of us stood. Practicing in the real exam format made test day feel much less unfamiliar. I stopped doing a huge amount one week and nothing the next. The group never had more than six students, so it was easy to stay involved. The preparation felt calmer than I expected.
