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!

The plan was adjusted when school exams became busy. We were happy with both the teaching and the communication.

Breaking AP Computer Science Principles into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. My written code answers became much more organized. I wasn't trying to learn new topics at the very last minute. I went into the exam much calmer than I would have before. I was really happy with the lessons.

I finally understood what was going wrong in AP European History. I learned to make a short plan before starting a long response. There was no overnight miracle, but the progress was easy to see.

I was doing questions for AP US Government on my own but never had a steady routine. The feedback I received on AP US Government was clear and practical. My tutor made it easy to ask questions from the first lesson. Connecting examples back to the main point made my writing more consistent. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.

Separating calculation errors from content gaps made revision more useful. I'm glad I worked with my tutor through this process.

After the first attempt, we looked for a calmer plan for the retake. The lessons started being followed without constant reminders from us. Mistakes became something to work on rather than something to feel bad about. Topic-based question practice made study time more focused. A good connection with the tutor developed quite quickly. Seeing the change in our child made us very happy.

Anxiety became more visible as the exam got closer. The lessons started being followed without constant reminders from us. Joining lessons willingly was one of the clearest signs for us. With no more than six students, the tutor had time for everyone. Mistakes became something to work on rather than something to feel bad about. We were pleased with the support we received.

Our child wasn't sure how to organize the preparation for AP Exams. The small group offered peer learning without making it hard to ask questions. The plan was adjusted when school exams became busy. The lessons started being followed without constant reminders from us. We thank the tutor and the TestPrep team.

I was close to my target, but my results changed a lot from one test to the next. I wasn't trying to learn new topics at the very last minute.

As the exam got closer, I wasn't sure what I should actually review. Over time, AP World History became one of the most organized parts of my AP Exams preparation. My tutor made it easy to ask questions from the first lesson. Source questions became easier once I noticed how small details affected the mark. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

The AP Exams format felt unnecessarily confusing at first. A big thank you to my tutor for all the support :)

When I started preparing for AP Exams, I wasn't sure what order to study things in. I never felt awkward asking the same thing again. After each test, we looked beyond the score and reviewed the type of each mistake. I became much more careful with graphs, experiments and data-based questions. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.

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. Lesson times could fit around school, university or work. I became much more careful with graphs, experiments and data-based questions. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.

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. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thank you to the tutor who stayed supportive until the end.

Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Art History into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. I understood that the portfolio needed to show the process, not only the finished piece. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
