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!

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
- 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
- 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
- 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
- IGCSE / GCSE
We wanted our child to keep up with the school pace in IGCSE English as a Second Language. Including assignments and internal exams made the plan sustainable. We quickly felt that the tutor was a good match.
Shelby Finley
- IGCSE / GCSE
I was doing questions for IGCSE English Literature on my own but never had a steady routine. The group never had more than six students, so it was easy to stay involved. Discussing why the other choices were wrong helped more than I expected. I stopped doing a huge amount one week and nothing the next. Even in a group lesson, the tutor knew where each of us stood. It was an intense period, but it was worth it.
Blake Nolan
- IGCSE / GCSE
I was doing questions for IGCSE Statistics on my own but never had a steady routine. My mock results gradually became more consistent.
Aditi Bedi
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. School assignments and internal exam dates were included in the schedule. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Pooja Ghosh
- IGCSE / GCSE
I was taking IGCSE Computer Science at school, but getting used to the exam questions took time. My tutor usually asked me to explain my thinking before stepping in. My written code answers became much more organized. I was really happy with the lessons.
Bea Santos
- IGCSE / GCSE
I finally understood what was going wrong in IGCSE Accounting. My case responses became more organized and direct. After a while, the questions started to feel much more familiar.
Nana Tamura
- IGCSE / GCSE
Our child wasn't sure how to organize the preparation for IGCSE / GCSE. Including assignments and internal exams made the plan sustainable. It was good to see confidence returning over time. A good connection with the tutor developed quite quickly. We thank the tutor and the TestPrep team.
Trevor Grady
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. My tutor could see my reasoning and usually found the source of an error quickly. Balancing Quant and Verbal in the same week worked better than studying them in blocks. 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. A big thank you to my tutor for all the support :)
Jules Delorme
- IGCSE / GCSE
Breaking IGCSE History into smaller pieces worked much better for me. I stopped listing facts in essays and started building an actual argument. There was no overnight miracle, but the progress was easy to see.
Josefina Paredes
- IGCSE / GCSE
I was doing questions for IGCSE Business Studies on my own but never had a steady routine. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. My case responses became more organized and direct. A big thank you to my tutor for all the support :)
Dimas Halim
- IGCSE / GCSE
Past-paper questions showed me how different topics could appear together. Thanks to TestPrep for helping me stay on track.
Minho Do
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. 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. I became much more careful with graphs, experiments and data-based questions. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
Merve Yucel
- IGCSE / GCSE
A good connection with the tutor developed quite quickly. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.
Ivan Kaminski
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. I'm glad I worked with my tutor through this process.
Hyejin Song
- IGCSE / GCSE
The feedback was clear enough that I always knew what to revise next. I'm glad I worked with my tutor through this process.
Spencer Barrett
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. We focused more on understanding what the problem asked than memorizing formulas. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Rina Miura
- IGCSE / GCSE
Breaking IGCSE English Literature into smaller pieces worked much better for me. My preparation became much more regular and easier to track.
Aoi Yoshida
- IGCSE / GCSE
We weren't sure whether online lessons would be effective. Regular mocks built familiarity with the real exam pace. We quickly felt that the tutor was a good match.
Eliza Whitlam
- IGCSE / GCSE
After the first attempt, we looked for a calmer plan for the retake. Being able to fit lessons around school made the process easier. Seeing the change in our child made us very happy.
