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!

Breaking AP World History into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.
Peng Luo
- Digital SAT
I chose Algebra this year and wanted to build a solid base from the beginning. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Learning when to leave a hard question made a real difference to my timing. The preparation felt calmer than I expected.
Ruoxi Yu
- GRE General
I came back to Section-Adaptive Strategy after a long break and wasn't sure where to begin. The feedback I received on Section-Adaptive Strategy was clear and practical. I stopped doing a huge amount one week and nothing the next. I worked on keeping a steady pace instead of rushing the easy questions. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.
Toby Ainsworth
- IB Diploma
The feedback I received on IB Geography was clear and practical. Using the mark scheme to review my own answer was surprisingly helpful. My preparation became much more regular and easier to track.
Joana Antunes
- A-Level
After the first attempt, we looked for a calmer plan for the retake. Online lessons made it possible to continue without losing time on travel. We thank the tutor and the TestPrep team.
Mitchell Hume
- IMAT
After my first attempt, I wanted the second round of preparation to feel more organized. Over time, General Knowledge became one of the most organized parts of my IMAT preparation. We could make the workload lighter during busy weeks at school or university. Using the mark scheme to review my own answer was surprisingly helpful. My mock results gradually became more consistent. It was an intense period, but it was worth it.
Imogen Farley
- IB Diploma
Our child wasn't sure how to organize the preparation for IB Diploma. We were pleased with the support we received.
Aditi Malhotra
- IB Diploma
We wanted our child to keep up with the school pace in IB Physics. The class size kept our child from disappearing into the background. We were able to follow the mock results regularly. Online lessons made it possible to continue without losing time on travel. We thank the tutor and the TestPrep team.
Harper Palmer
- AP Exams
Discussing why the other choices were wrong helped more than I expected. I'm genuinely thankful to my tutor for being patient.
Seojun Ma
- Digital SAT
The tutor supported regular study, not only the lesson content. Preparation looked calmer and more organized closer to the exam. Seeing the change in our child made us very happy.
Sungmin Heo
- A-Level
A good connection with the tutor developed quite quickly. Preparation looked calmer and more organized closer to the exam. We were happy with both the teaching and the communication.
Zhihao Dong
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor usually asked me to explain my thinking before stepping in. 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. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.
Margaux Tessier
- IB Diploma
It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. We quickly felt that the tutor was a good match.
Joel OBrien
- IGCSE / GCSE
The feedback I received on IGCSE Psychology was clear and practical. Connecting examples back to the main point made my writing more consistent. After a while, the questions started to feel much more familiar.
Marit Peters
- A-Level
Over time, A-Level Physics became one of the most organized parts of my A-Level preparation. Past-paper questions showed me how different topics could appear together. There was no overnight miracle, but the progress was easy to see.
Aurora Costa
- IGCSE / GCSE
The feedback I received on IGCSE Economics was clear and practical. I went into the exam much calmer than I would have before.
Tomas Novak
- Digital SAT
As the exam got closer, I wasn't sure what I should actually review. Over time, Problem Solving & Data Analysis became one of the most organized parts of my Digital SAT preparation. The plan changed with my mock and homework results, so the work never felt random. I started seeing shorter solutions that were easier to check under time pressure. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.
Pauline Millet
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. 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. By the end of each lesson, I knew what I was supposed to do during the week. We didn't spend extra time on things I already knew. I'm glad I worked with my tutor through this process.
Linh Huynh
- Digital SAT
I chose Expression of Ideas this year and wanted to build a solid base from the beginning. Working across different difficulty levels made new questions feel less surprising. I left the exam feeling that I had done what I could. The preparation felt calmer than I expected.
Finn Goodall
- IGCSE / GCSE
Everyone recommended different resources and I kept switching between them. I finally understood what was going wrong in IGCSE Biology. One bad mock no longer made me want to drop the whole plan. Once I understood the reasons behind the facts, the questions felt less random. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.
Danica Peric
- GRE General
I knew my target, but I didn't have a realistic routine for GRE General. Having the lesson move at my pace made the process feel much easier. I worked on keeping a steady pace instead of rushing the easy questions. I started tracking the type of mistake, not just the number of questions I completed. It was an intense period, but it was worth it.
Kenta Ito
- GRE General
I had been studying alone, but my results stopped improving after a point. I'm glad I worked with my tutor through this process.
Kiara Rowntree
- TOEFL iBT
I finally understood what was going wrong in Reading. My preparation became much more regular and easier to track.
Lucie Perrin
- Digital SAT
What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. I can now decide much faster when to move on from a question. Thanks to TestPrep for helping me stay on track.
