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!

Over time, AP Physics C: E&M became one of the most organized parts of my AP Exams preparation. I started noticing the reason for a mistake much faster.
Eduardo Castro
- AP Exams
Using the mark scheme to review my own answer was surprisingly helpful. I was really happy with the lessons.
Levi Langford
- AP Exams
I was close to my target, but my results changed a lot from one test to the next. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. After each test, we looked beyond the score and reviewed the type of each mistake. The lessons where I found the bug myself were the ones I remembered best. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.
Alan Varela
- IGCSE / GCSE
Our child wasn't sure how to organize the preparation for IGCSE / GCSE. Returning to actual gaps instead of restarting everything saved time. It was good to see confidence returning over time. Flexible scheduling helped during a demanding school year. Seeing the change in our child made us very happy.
Lara Jansen
- IB Diploma
I finally understood what was going wrong in IB English A. There was no overnight miracle, but the progress was easy to see.
Renata Nascimento
- SSAT
Breaking Writing Sample into smaller pieces worked much better for me. My written answers became shorter, clearer and easier to follow. I left the exam feeling that I had done what I could.
Luana Gomes
- Digital SAT
I was taking Information & Ideas at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. Choosing questions by topic made my practice time much more useful. Timed work showed exactly which section was slowing me down. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.
Levi Newell
- IMAT
At the beginning, we knew very little about the IMAT system as parents. Flexible scheduling helped during a demanding school year. Regular work on similar question types reduced repeated mistakes. Online lessons made it possible to continue without losing time on travel. The plan was adjusted when school exams became busy. We would recommend the program to students and families in a similar situation.
Jimena Peralta
- Digital SAT
Keeping up with Digital SAT while school was busy was harder than I expected. I went into the exam much calmer than I would have before.
Riley Mallory
- IGCSE / GCSE
After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in IGCSE Physics. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.
Andrea Neri
- IGCSE / GCSE
I was taking IGCSE Mathematics at school, but getting used to the exam questions took time. I started noticing the reason for a mistake much faster.
Kiara Kirk
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. I left the exam feeling that I had done what I could.
Juliette Lambert
- LNAT
The feedback I received on Section B Essay was clear and practical. Discussing why the other choices were wrong helped more than I expected. After a while, the questions started to feel much more familiar.
Liam Stanton
- YÖS / TR-YÖS
Everyone recommended different resources and I kept switching between them. I went into the exam much calmer than I would have before.
Eunji Ahn
- UCAT
I was doing questions for Situational Judgement on my own but never had a steady routine. Thank you to the tutor who stayed supportive until the end.
Kyungsoo Ma
- LSAT
Balancing LSAT preparation with university and work was harder than I expected. I finally understood what was going wrong in Argumentative Writing. My tutor made it easy to ask questions from the first lesson. I learned not to spend the same amount of time on every line of a long text. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.
Caitlin Vickers
- AP Exams
We wanted our child to keep up with the school pace in AP Seminar. Past-paper work continued without falling behind in current school topics. Thank you sincerely to everyone involved.
Catalina Palacios
- AP Exams
I was doing questions for AP English Language on my own but never had a steady routine. We didn't spend extra time on things I already knew. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.
Paolo Macapagal
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. By the end of each lesson, I knew what I was supposed to do during the week. Past-paper questions showed me how different topics could appear together. I'm glad I worked with my tutor through this process.
Kaan Celik
- A-Level
Everyone recommended different resources and I kept switching between them. I never felt awkward asking the same thing again. Predicting the output helped me catch small logic errors. I'm glad I worked with my tutor through this process.
Meilin Li
- IGCSE / GCSE
I was doing questions for IGCSE Statistics on my own but never had a steady routine. Full-length mocks helped me get used to the real exam pace. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
Devin Russell
- SSAT
After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. Timed work showed exactly which section was slowing me down. I stopped doing a huge amount one week and nothing the next. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.
Bjorn Novak
- Digital SAT
We noticed that the resources kept changing during independent study. With no more than six students, the tutor had time for everyone. The tutor supported regular study, not only the lesson content. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Grant Maxwell
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. By the end of each lesson, I knew what I was supposed to do during the week. My tutor could see my reasoning and usually found the source of an error quickly. Discussing why the other choices were wrong helped more than I expected. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.
