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!

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We balanced current school topics with past-paper practice. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.
Hao Cao
- GMAT Focus
Balancing GMAT Focus preparation with university and work was harder than I expected. The plan changed with my mock and homework results, so the work never felt random. A quick check after each answer helped me catch small mistakes. Thanks to TestPrep for helping me stay on track.
Annika Kristensen
- IGCSE / GCSE
Over time, IGCSE Economics became one of the most organized parts of my IGCSE / GCSE preparation. Balancing Quant and Verbal in the same week worked better than studying them in blocks. My mock results gradually became more consistent.
Pim Inthara
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. Having the lesson move at my pace made the process feel much easier. Using the mark scheme to review my own answer was surprisingly helpful. I stopped doing a huge amount one week and nothing the next. My tutor could see my reasoning and usually found the source of an error quickly. The preparation felt calmer than I expected.
Declan Langford
- ACT
As the exam got closer, I wasn't sure what I should actually review. Full-length mocks helped me get used to the real exam pace. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Ren Kaneko
- IB Diploma
Everyone recommended different resources and I kept switching between them. I wasn't trying to learn new topics at the very last minute.
Hyunwoo Sim
- GMAT Focus
I came back to Reading Comprehension after a long break and wasn't sure where to begin. We could make the workload lighter during busy weeks at school or university. After each test, we looked beyond the score and reviewed the type of each mistake. Discussing why the other choices were wrong helped more than I expected. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Declan Jarvis
- IB Diploma
I was taking Theory of Knowledge (TOK) at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. We were realistic about what could be improved in the time available. The feedback helped me improve my own work without writing it for me. I left the exam feeling that I had done what I could. Thanks to TestPrep for helping me stay on track.
Klara Visser
- IELTS Academic
Over time, Speaking became one of the most organized parts of my IELTS Academic preparation. I left the exam feeling that I had done what I could.
Irem Tekin
- A-Level
Our child wasn't sure how to organize the preparation for A-Level. The lessons started being followed without constant reminders from us. Individual lesson time was used around our child's actual needs. Mistakes became something to work on rather than something to feel bad about. The tutor supported regular study, not only the lesson content. Thank you sincerely to everyone involved.
Connor Fletcher
- SSAT
I was doing questions for Writing Sample on my own but never had a steady routine. Near the exam, it was clear what to keep doing and what to stop. Discussing why the other choices were wrong helped more than I expected. A big thank you to my tutor for all the support :)
Piper Reynolds
- IB Diploma
Breaking Extended Essay (EE) into smaller pieces worked much better for me. My mock results gradually became more consistent.
Diogo Cabrera
- IGCSE / GCSE
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. The group never had more than six students, so it was easy to stay involved. Past-paper questions showed me how different topics could appear together. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.
Yash Sen
- AP Exams
The AP Exams format felt unnecessarily confusing at first. After each test, we looked beyond the score and reviewed the type of each mistake. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.
Agustina Solis
- TOEFL iBT
I finally understood what was going wrong in Writing. I found a better balance between regular school and exam preparation.
Amelie Delorme
- AP Exams
The lessons where I found the bug myself were the ones I remembered best. It was an intense period, but it was worth it.
Johan Holm
- AP Exams
Having the lesson move at my pace made the process feel much easier. Over time, AP Physics C: Mechanics became one of the most organized parts of my AP Exams preparation. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.
Marissa Harrington
- A-Level
At the beginning, we knew very little about the A-Level system as parents. Preparation looked calmer and more organized closer to the exam. Communication with the team was straightforward and our questions were answered. Being able to fit lessons around school made the process easier. We were able to follow the mock results regularly. We would recommend the program to students and families in a similar situation.
Arjun Arora
- AP Exams
I finally understood what was going wrong in AP Statistics. We focused more on understanding what the problem asked than memorizing formulas. I found a better balance between regular school and exam preparation.
Sooyoung Kang
- GMAT Focus
I had been studying alone, but my results stopped improving after a point. My confidence improved along with the results.
Trent Aldridge
- IB Diploma
Over time, IB Psychology became one of the most organized parts of my IB Diploma preparation. The plan changed with my mock and homework results, so the work never felt random. I stopped listing facts in essays and started building an actual argument. My confidence improved along with the results. I left the exam feeling that I had done what I could. I was really happy with the lessons.
Yash Menon
- A-Level
The feedback I received on A-Level English Literature was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Discussing why the other choices were wrong helped more than I expected. My preparation became much more regular and easier to track. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Joel Whitman
- LNAT
Everyone recommended different resources and I kept switching between them. The preparation felt calmer than I expected.
Nuria Pastor
- IB Diploma
Over time, IB Turkish A became one of the most organized parts of my IB Diploma preparation. I went into the exam much calmer than I would have before.
