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. I used the question bank regularly to return to weaker topics. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.

Balancing GMAT Focus preparation with university and work was harder than I expected. There was no overnight miracle, but the progress was easy to see.

I finally understood what was going wrong in Section B Essay. A lot of my mistakes came from rushing through the wording of the question. My preparation became much more regular and easier to track.

Anxiety became more visible as the exam got closer. The class size kept our child from disappearing into the background. Preparation looked calmer and more organized closer to the exam. Joining lessons willingly was one of the clearest signs for us. We were happy with both the teaching and the communication.
Zeynep Tekin
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We could make the workload lighter during busy weeks at school or university. Having the lesson move at my pace made the process feel much easier. I worked on keeping a steady pace instead of rushing the easy questions. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.

Leandro Teixeira
- A-Level
The A-Level format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. I learned to separate the information needed for a decision from the extra detail. The preparation felt calmer than I expected.
