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!

When I started preparing for IB Diploma, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

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.

Our daughter needed regular support with IGCSE Business Studies. Thank you sincerely to everyone involved.

Breaking Verbal Reasoning into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. Discussing why the other choices were wrong helped more than I expected. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

- GRE General
I had been studying alone, but my results stopped improving after a point. Working across different difficulty levels made new questions feel less surprising. After a while, the questions started to feel much more familiar. Thanks to everyone who supported me.

Our son's school schedule was already very busy. Mistakes became something to work on rather than something to feel bad about. Communication with the team was straightforward and our questions were answered. Full-length tests showed how time was being used across the exam. The plan was adjusted when school exams became busy. Thank you sincerely to everyone involved.

I was doing questions for IB Physics on my own but never had a steady routine. The plan changed with my mock and homework results, so the work never felt random. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thank you to my tutor and the TestPrep team.

We weren't sure whether online lessons would be effective. We were able to follow the mock results regularly. The plan was adjusted when school exams became busy. The tutor's close attention to weaker areas gave us confidence. It was good to see confidence returning over time. We were pleased with the support we received.

At the beginning, we knew very little about the ACT system as parents. The tutor's close attention to weaker areas gave us confidence. Online lessons made it possible to continue without losing time on travel. Communication with the team was straightforward and our questions were answered. Seeing the change in our child made us very happy.
