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!

As the exam got closer, I wasn't sure what I should actually review. I finally understood what was going wrong in IB Psychology. One bad mock no longer made me want to drop the whole plan. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. A big thank you to my tutor for all the support :)

Breaking Mathematics into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. Learning when to leave a hard question made a real difference to my timing. I found a better balance between regular school and exam preparation. My preparation became much more regular and easier to track. Thanks to TestPrep for helping me stay on track.
Marina Almeida
- A-Level
I was taking A-Level Mathematics at school, but getting used to the exam questions took time. My tutor usually asked me to explain my thinking before stepping in. Working across different difficulty levels made new questions feel less surprising. Learning when to leave a hard question made a real difference to my timing. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

Joining lessons willingly was one of the clearest signs for us. We quickly felt that the tutor was a good match.
Fajar Ramadhan
- IGCSE / GCSE
After the first attempt, we looked for a calmer plan for the retake. The lessons started being followed without constant reminders from us. Preparation looked calmer and more organized closer to the exam. Past-paper work continued without falling behind in current school topics. The plan was adjusted when school exams became busy. We quickly felt that the tutor was a good match.

I finally understood what was going wrong in Mathematics. I wasn't trying to learn new topics at the very last minute.
Valentin Berger
- AP Exams
I was doing questions for AP Art History on my own but never had a steady routine. One bad mock no longer made me want to drop the whole plan. Splitting time between research, making and editing kept the work manageable. Thank you to my tutor and the TestPrep team.
Jasmine Newell
- UCAT
Our daughter needed regular support with Situational Judgement. The lessons started being followed without constant reminders from us. The class size kept our child from disappearing into the background. Joining lessons willingly was one of the clearest signs for us. The plan was adjusted when school exams became busy. Seeing the change in our child made us very happy.

Anxiety became more visible as the exam got closer. We were happy with both the teaching and the communication.
Mei Fujita
- IGCSE / GCSE
I chose IGCSE Business Studies this year and wanted to build a solid base from the beginning. I stopped doing a huge amount one week and nothing the next. Choosing questions by topic made my practice time much more useful. With data-heavy questions, I began reading the task before getting lost in the table. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Buse Akbulut
- IMAT
The feedback I received on Mathematics was clear and practical. My tutor usually asked me to explain my thinking before stepping in. Seeing several versions of the same topic made unfamiliar questions less stressful. Knowing what to study reduced a lot of the stress. I started noticing the reason for a mistake much faster. Thanks to TestPrep for helping me stay on track.
Mitali Verma
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. Near the exam, it was clear what to keep doing and what to stop. I learned to make a short plan before starting a long response. I was really happy with the lessons.
Jack Palmer
- IB Diploma
What annoyed me most was losing easy points because I rushed. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. During the intensive review, we returned to real gaps instead of restarting everything. Separating strategy mistakes from content gaps made progress much quicker. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.
Thais Leite
- SSAT
Keeping up with SSAT while school was busy was harder than I expected. I used the question bank regularly to return to weaker topics. My confidence improved along with the results. Thank you to my tutor and the TestPrep team.
Mitchell Corbett
- UCAT
As the exam got closer, I wasn't sure what I should actually review. I stopped doing a huge amount one week and nothing the next. During the intensive review, we returned to real gaps instead of restarting everything. A quick check after each answer helped me catch small mistakes. After a while, the questions started to feel much more familiar. The preparation felt calmer than I expected.
Lihua Song
- IMAT
I was taking Biology at school, but getting used to the exam questions took time. Breaking Biology into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.
Miku Murakami
- UCAT
We wanted our child to keep up with the school pace in Decision Making. Mock analysis allowed us to follow progress more clearly. The plan was adjusted when school exams became busy. The tutor supported regular study, not only the lesson content. The overall experience was positive from beginning to end.
Avery Fletcher
- LSAT
I had been studying alone, but my results stopped improving after a point. The plan changed with my mock and homework results, so the work never felt random. Having the lesson move at my pace made the process feel much easier. My written answers became shorter, clearer and easier to follow. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Antoine Perrin

When I started preparing for IB Diploma, I wasn't sure what order to study things in. Full-length mocks helped me get used to the real exam pace. My mock results gradually became more consistent. Thanks to everyone who supported me.

Past-paper questions showed me how different topics could appear together. A big thank you to my tutor for all the support :)

I finally understood what was going wrong in Elementary Level. Timed work showed exactly which section was slowing me down. I wasn't trying to learn new topics at the very last minute.
Nayeon Guk
- AP Exams
Our child wasn't sure how to organize the preparation for AP Exams. Flexible scheduling helped during a demanding school year. Being able to fit lessons around school made the process easier. A good connection with the tutor developed quite quickly. Communication with the team was straightforward and our questions were answered. We thank the tutor and the TestPrep team.
Rui Yuan
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. I started tracking the type of mistake, not just the number of questions I completed. A quick check after each answer helped me catch small mistakes. I was really happy with the lessons.
