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!

After each test, we looked beyond the score and reviewed the type of each mistake. Over time, AP Physics C: Mechanics became one of the most organized parts of my AP Exams preparation. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.

I was doing questions for AP English Language on my own but never had a steady routine. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. Thanks to everyone who supported me.

Keeping up with AP Exams while school was busy was harder than I expected. The group never had more than six students, so it was easy to stay involved. Knowing the criteria from the start made the whole task less vague. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Even in a group lesson, the tutor knew where each of us stood. I was really happy with the lessons.
