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!

Our son's school schedule was already very busy. It was good to see confidence returning over time. We were pleased with the support we received.

I chose AP Physics 1 this year and wanted to build a solid base from the beginning. My tutor made it easy to ask questions from the first lesson. Lesson times could fit around school, university or work. I became much more careful with graphs, experiments and data-based questions. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

Lesson times could fit around school, university or work. Breaking AP Biology into smaller pieces worked much better for me. I found a better balance between regular school and exam preparation. The preparation felt calmer than I expected.

Anxiety became more visible as the exam got closer. Mistakes became something to work on rather than something to feel bad about. We were pleased with the support we received.

Mistakes became something to work on rather than something to feel bad about. We would recommend the program to students and families in a similar situation.

What annoyed me most was losing easy points because I rushed. Even in a group lesson, the tutor knew where each of us stood. I found a better balance between regular school and exam preparation. A big thank you to my tutor for all the support :)

Even in a group lesson, the tutor knew where each of us stood. I finally understood what was going wrong in AP Environmental Science. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.

I chose AP Physics C: Mechanics this year and wanted to build a solid base from the beginning. One bad mock no longer made me want to drop the whole plan. Once I understood the reasons behind the facts, the questions felt less random. Thank you to my tutor and the TestPrep team.

Nana Ogawa

I was close to my target, but my results changed a lot from one test to the next. Near the exam, it was clear what to keep doing and what to stop. Lesson times could fit around school, university or work. I started seeing shorter solutions that were easier to check under time pressure. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

At the beginning, we knew very little about the AP Exams system as parents. We were able to follow the mock results regularly. Joining lessons willingly was one of the clearest signs for us. Returning to actual gaps instead of restarting everything saved time. The lessons started being followed without constant reminders from us. Seeing the change in our child made us very happy.

We focused more on understanding what the problem asked than memorizing formulas. It was an intense period, but it was worth it.
Catarina Campos
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. The class felt relaxed enough to ask questions without overthinking it. Connecting examples back to the main point made my writing more consistent. One bad mock no longer made me want to drop the whole plan. Questions from other students often helped me as well. I'm glad I worked with my tutor through this process.
