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 my first attempt, I wanted the second round of preparation to feel more organized. My tutor usually asked me to explain my thinking before stepping in. After enough examples of the same question type, the repeated mistakes decreased. The writing feedback helped me stop repeating the same sentence-level errors. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

I finally understood what was going wrong in Logical Reasoning. I started noticing the reason for a mistake much faster.
Matias Figueroa
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Going back to the lesson recordings helped when I forgot a small step. Using the mark scheme to review my own answer was surprisingly helpful. Thanks to everyone who supported me.

Anxiety became more visible as the exam got closer. The lessons started being followed without constant reminders from us. We were pleased with the support we received.

The feedback I received on AP Physics C: Mechanics was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. I became much more careful with graphs, experiments and data-based questions. I went into the exam much calmer than I would have before. I started noticing the reason for a mistake much faster. I was really happy with the lessons.

I was taking AP Chemistry at school, but getting used to the exam questions took time. One bad mock no longer made me want to drop the whole plan. Having the lesson move at my pace made the process feel much easier. 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.

Keeping up with A-Level while school was busy was harder than I expected. My tutor could see my reasoning and usually found the source of an error quickly. I went into the exam much calmer than I would have before. I was really happy with the lessons.

The AP Exams format felt unnecessarily confusing at first. Thanks to everyone who supported me.

We were able to follow the mock results regularly. We quickly felt that the tutor was a good match.
Lucie Faure

Breaking A-Level English Literature into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. Discussing why the other choices were wrong helped more than I expected. My confidence improved along with the results. There was no overnight miracle, but the progress was easy to see. Thanks to TestPrep for helping me stay on track.

The class felt relaxed enough to ask questions without overthinking it. The feedback I received on A-Level Computer Science was clear and practical. I wasn't trying to learn new topics at the very last minute. A big thank you to my tutor for all the support :)

Rahul Dutta
- Digital SAT
The feedback I received on Standard English Conventions was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. A lot of my mistakes came from rushing through the wording of the question. I left the exam feeling that I had done what I could. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.
Ryota Kimura
- IB Diploma
Focusing on past papers and mock review worked well near the exam. Breaking IB Biology into smaller pieces worked much better for me. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)
Marta Cunha
- IMAT
What annoyed me most was losing easy points because I rushed. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.

- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. Over time, IGCSE Chemistry became one of the most organized parts of my IGCSE / GCSE preparation. Near the exam, it was clear what to keep doing and what to stop. I became much more careful with graphs, experiments and data-based questions. There was no overnight miracle, but the progress was easy to see. Thanks to TestPrep for helping me stay on track.
