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 doing questions for AP Computer Science A on my own but never had a steady routine. I never felt awkward asking the same thing again. During the intensive review, we returned to real gaps instead of restarting everything. The lessons where I found the bug myself were the ones I remembered best. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

We didn't spend extra time on things I already knew. I finally understood what was going wrong in AP Physics 1. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.

What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. We didn't spend extra time on things I already knew. I learned to separate the information needed for a decision from the extra detail. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.

What annoyed me most was losing easy points because I rushed. The feedback I received on AP World History was clear and practical. 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 found a better balance between regular school and exam preparation. I was really happy with the lessons.

We wanted our child to keep up with the school pace in AP US History. The tutor's close attention to weaker areas gave us confidence. We were pleased with the support we received.

Keeping up with AP Exams while school was busy was harder than I expected. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. With data-heavy questions, I began reading the task before getting lost in the table. Thanks to TestPrep for helping me stay on track.

Over time, AP Biology 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. Separating calculation errors from content gaps made revision more useful. I went into the exam much calmer than I would have before. Knowing what to study reduced a lot of the stress. Thank you to my tutor and the TestPrep team.

When I started preparing for AP Exams, I wasn't sure what order to study things in. We didn't spend extra time on things I already knew. Past-paper questions showed me how different topics could appear together. I started tracking the type of mistake, not just the number of questions I completed. Having the lesson move at my pace made the process feel much easier. Thank you to my tutor and the TestPrep team.

We noticed that the resources kept changing during independent study. We quickly felt that the tutor was a good match.

I chose AP Physics C: E&M this year and wanted to build a solid base from the beginning. Breaking AP Physics C: E&M into smaller pieces worked much better for me. I never felt awkward asking the same thing again. Once I understood the reasons behind the facts, the questions felt less random. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

I was taking AP English Literature at school, but getting used to the exam questions took time. Breaking AP English Literature into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I learned not to spend the same amount of time on every line of a long text. I went into the exam much calmer than I would have before. Thank you to the tutor who stayed supportive until the end.

At the beginning, we knew very little about the AP Exams system as parents. A realistic plan for the final weeks reduced stress for the whole family. We thank the tutor and the TestPrep team.

I was taking AP Physics 2 at school, but getting used to the exam questions took time. We didn't spend extra time on things I already knew. I became much more careful with graphs, experiments and data-based questions. I started tracking the type of mistake, not just the number of questions I completed. Thank you to my tutor and the TestPrep team.

After the first attempt, we looked for a calmer plan for the retake. Communication with the team was straightforward and our questions were answered. Flexible scheduling helped during a demanding school year. A realistic plan for the final weeks reduced stress for the whole family. The plan was adjusted when school exams became busy. Seeing the change in our child made us very happy.

Everyone recommended different resources and I kept switching between them. The mocks showed where my time was actually being lost. Once I understood the reasons behind the facts, the questions felt less random. Going back to the lesson recordings helped when I forgot a small step. Full-length mocks helped me get used to the real exam pace. The preparation felt calmer than I expected.

We noticed that the resources kept changing during independent study. Past-paper work continued without falling behind in current school topics.

When I started preparing for AP Exams, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. My case responses became more organized and direct. Thanks to TestPrep for helping me stay on track.

Our daughter needed regular support with AP European History. Preparation looked calmer and more organized closer to the exam. The tutor supported regular study, not only the lesson content. The class size kept our child from disappearing into the background. Flexible scheduling helped during a demanding school year. We were happy with both the teaching and the communication.
