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!

Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. My preparation became much more regular and easier to track.
Leon Neumann
- YÖS / TR-YÖS
I chose Geometry this year and wanted to build a solid base from the beginning. Going back to the lesson recordings helped when I forgot a small step. Having the lesson move at my pace made the process feel much easier. We focused more on understanding what the problem asked than memorizing formulas. I became much more comfortable asking questions in class. I was really happy with the lessons.
Mathis Lacroix
- YÖS / TR-YÖS
The YÖS / TR-YÖS format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.

The feedback I received on Mathematics was clear and practical. After a while, the questions started to feel much more familiar.
Paula Mendoza
- YÖS / TR-YÖS
Breaking Mathematics into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. Learning when to leave a hard question made a real difference to my timing. I started noticing the reason for a mistake much faster. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.

A good connection with the tutor developed quite quickly. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Nils Ahlberg
- YÖS / TR-YÖS
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. The plan changed with my mock and homework results, so the work never felt random. Having the lesson move at my pace made the process feel much easier. A quick check after each answer helped me catch small mistakes. I wasn't trying to learn new topics at the very last minute. The preparation felt calmer than I expected.
Meera Kulkarni
- YÖS / TR-YÖS
We weren't sure whether online lessons would be effective. With no more than six students, the tutor had time for everyone. The lessons started being followed without constant reminders from us. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.

I was really happy with the lessons.
Lorenzo Rossetti
- YÖS / TR-YÖS

Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. Joining lessons willingly was one of the clearest signs for us.
