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 feedback I received on AP Physics C: Mechanics was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. I became much more careful with graphs, experiments and data-based questions. I went into the exam much calmer than I would have before. I started noticing the reason for a mistake much faster. I was really happy with the lessons.

I was taking AP Chemistry at school, but getting used to the exam questions took time. One bad mock no longer made me want to drop the whole plan. Having the lesson move at my pace made the process feel much easier. I became much more careful with graphs, experiments and data-based questions. My confidence improved along with the results. The preparation felt calmer than I expected.

Everyone recommended different resources and I kept switching between them. Focusing on past papers and mock review worked well near the exam. My written code answers became much more organized. My tutor made it easy to ask questions from the first lesson. We were realistic about what could be improved in the time available. The preparation felt calmer than I expected.

I was close to my target, but my results changed a lot from one test to the next. I was really happy with the lessons.

Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Calculus BC into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. I started seeing shorter solutions that were easier to check under time pressure. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.

I was really happy with the lessons.

At the beginning, we knew very little about the AP Exams system as parents. Online lessons made it possible to continue without losing time on travel.

I chose AP Chemistry this year and wanted to build a solid base from the beginning. My tutor usually asked me to explain my thinking before stepping in. Past-paper questions showed me how different topics could appear together. Thanks to TestPrep for helping me stay on track.

After my first attempt, I wanted the second round of preparation to feel more organized. I never felt awkward asking the same thing again. Lesson times could fit around school, university or work. I realized that choosing a topic, researching and revising each needed its own deadline. My mock results gradually became more consistent. Thank you to the tutor who stayed supportive until the end.

I was doing questions for AP Psychology on my own but never had a steady routine. Breaking AP Psychology into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. I stopped listing facts in essays and started building an actual argument. I found a better balance between regular school and exam preparation. 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. My tutor usually asked me to explain my thinking before stepping in. Choosing questions by topic made my practice time much more useful. We focused more on understanding what the problem asked than memorizing formulas. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

Over time, AP Microeconomics became one of the most organized parts of my AP Exams preparation. Separating strategy mistakes from content gaps made progress much quicker. I started noticing the reason for a mistake much faster.

At the beginning, we knew very little about the AP Exams system as parents. The tutor's close attention to weaker areas gave us confidence. We quickly felt that the tutor was a good match.

Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. We would recommend the program to students and families in a similar situation.

Breaking AP Physics 1 into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.
Catalina Villalba
- AP Exams
After my first attempt, I wanted the second round of preparation to feel more organized. Over time, AP Physics C: Mechanics became one of the most organized parts of my AP Exams preparation. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.

Our child had a clear goal but no steady study routine. Individual lesson time was used around our child's actual needs. The plan was adjusted when school exams became busy. We were able to follow the mock results regularly. Seeing the change in our child made us very happy.

After each test, we looked beyond the score and reviewed the type of each mistake. Breaking AP Human Geography into smaller pieces worked much better for me. My confidence improved along with the results. Thank you to the tutor who stayed supportive until the end.
