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!

I was taking AP Calculus AB at school, but getting used to the exam questions took time. I could work on exam technique without falling behind in class. We focused more on understanding what the problem asked than memorizing formulas. The plan changed with my mock and homework results, so the work never felt random. I'm glad I worked with my tutor through this process.

Over time, AP Research became one of the most organized parts of my AP Exams preparation. Near the exam, it was clear what to keep doing and what to stop. I realized that choosing a topic, researching and revising each needed its own deadline. I left the exam feeling that I had done what I could. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.

We noticed that the resources kept changing during independent study. The tutor supported regular study, not only the lesson content. Topic-based question practice made study time more focused. It was good to see confidence returning over time. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.

The AP Exams format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.

We wanted our child to keep up with the school pace in AP European History. We quickly felt that the tutor was a good match.

I was close to my target, but my results changed a lot from one test to the next. Breaking AP Physics C: E&M into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I became much more careful with graphs, experiments and data-based questions. My mock results gradually became more consistent. It was an intense period, but it was worth it.

Keeping up with AP Exams while school was busy was harder than I expected. The feedback I received on AP European History was clear and practical. We could make the workload lighter during busy weeks at school or university. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

Everyone recommended different resources and I kept switching between them. By the end of each lesson, I knew what I was supposed to do during the week. Before coding, I began thinking about which structure actually fit the problem. It was an intense period, but it was worth it.

Breaking AP Physics 1 into smaller pieces worked much better for me. I became much more comfortable asking questions in class.

Everyone recommended different resources and I kept switching between them. Having the lesson move at my pace made the process feel much easier. I started tracing code line by line instead of only reading it quickly. We could make the workload lighter during busy weeks at school or university. My tutor could see my reasoning and usually found the source of an error quickly. It was an intense period, but it was worth it.

The AP Exams format felt unnecessarily confusing at first. I used the question bank regularly to return to weaker topics. I found a better balance between regular school and exam preparation. I'm glad I worked with my tutor through this process.

What annoyed me most was losing easy points because I rushed. Breaking AP Microeconomics into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. Separating strategy mistakes from content gaps made progress much quicker. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

Our son's school schedule was already very busy. We were able to follow the mock results regularly. Mistakes became something to work on rather than something to feel bad about. The tutor's close attention to weaker areas gave us confidence. The tutor supported regular study, not only the lesson content. We quickly felt that the tutor was a good match.

Breaking AP European History into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Connecting examples back to the main point made my writing more consistent. I went into the exam much calmer than I would have before. My confidence improved along with the results. Thank you to my tutor and the TestPrep team.

Our child had a clear goal but no steady study routine. Joining lessons willingly was one of the clearest signs for us. Online lessons made it possible to continue without losing time on travel. Full-length tests showed how time was being used across the exam. The overall experience was positive from beginning to end.
