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 IB World History into smaller pieces worked much better for me. I stopped listing facts in essays and started building an actual argument. I found a better balance between regular school and exam preparation.

- IGCSE / GCSE
I chose IGCSE Chemistry this year and wanted to build a solid base from the beginning. One bad mock no longer made me want to drop the whole plan. I became much more careful with graphs, experiments and data-based questions. Thank you to my tutor and the TestPrep team.
Nolan Vaughn
- AP Exams
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We could make the workload lighter during busy weeks at school or university. Lesson times could fit around school, university or work. I became much more careful with graphs, experiments and data-based questions. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.
Diogo Leitao
- UCAT
Keeping up with UCAT while school was busy was harder than I expected. Full-length mocks helped me get used to the real exam pace. Seeing several versions of the same topic made unfamiliar questions less stressful. I never felt awkward asking the same thing again. Experiencing the exam format beforehand made test day much less stressful. It was an intense period, but it was worth it.
Devin Prescott
- SSAT
The SSAT format felt unnecessarily confusing at first. The feedback I received on Upper Level was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Practicing in the real exam format made test day feel much less unfamiliar. Knowing what to study reduced a lot of the stress. I'm glad I worked with my tutor through this process.
Chaewon Nam
- PTE Academic
Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.
Taeho Oh
- TOEFL iBT
The feedback I received on Reading was clear and practical. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I found a better balance between regular school and exam preparation.
Declan Langley
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. One bad mock no longer made me want to drop the whole plan. Practicing in the real exam format made test day feel much less unfamiliar. Thanks to TestPrep for helping me stay on track.
Jade Lawson
- IB Diploma
I was taking IB Mathematics AI at school, but getting used to the exam questions took time. I finally understood what was going wrong in IB Mathematics AI. I stopped doing a huge amount one week and nothing the next. I started seeing shorter solutions that were easier to check under time pressure. I left the exam feeling that I had done what I could. Thank you to my tutor and the TestPrep team.
Fajar Susanto
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thank you to the tutor who stayed supportive until the end.
Ruby Harcourt
- IB Diploma
I chose IB Visual Arts this year and wanted to build a solid base from the beginning. A big thank you to my tutor for all the support :)
Zuzana Lund
- IELTS Academic
Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. We were happy with both the teaching and the communication.
Javier Barros
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. My tutor could see my reasoning and usually found the source of an error quickly. A lot of my mistakes came from rushing through the wording of the question. My tutor usually asked me to explain my thinking before stepping in. We didn't spend extra time on things I already knew. I'm genuinely thankful to my tutor for being patient.
Tobias Baumann
- TOEFL iBT
We noticed that the resources kept changing during independent study. The class size kept our child from disappearing into the background. We quickly felt that the tutor was a good match.
Tanvi Banerjee
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Art History into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. I understood that the portfolio needed to show the process, not only the finished piece. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
Harry Ellis
- SSAT
After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in Reading. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.
Sydney Harrington
- A-Level
Breaking A-Level Further Mathematics into smaller pieces worked much better for me. I became much more comfortable asking questions in class.
Volkan Ekinci
- SSAT
I was taking Upper Level at school, but getting used to the exam questions took time. The mocks showed where my time was actually being lost. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.
Haeun Heo
- AP Exams
Preparation looked calmer and more organized closer to the exam. We were able to follow the mock results regularly. We were happy with both the teaching and the communication.
Masato Maeda
- IGCSE / GCSE
The feedback I received on IGCSE Geography was clear and practical. Using the mark scheme to review my own answer was surprisingly helpful. After a while, the questions started to feel much more familiar.
Flynn Bevan
- AP Exams
I finally understood what was going wrong in AP World History. Connecting examples back to the main point made my writing more consistent. I started noticing the reason for a mistake much faster.
Miku Matsumoto
- GRE General
In Analytical Writing, timing was costing me more points than the content itself. The preparation felt calmer than I expected.
Seo Yang
- IELTS Academic
I was doing questions for Listening on my own but never had a steady routine. Even in a group lesson, the tutor knew where each of us stood. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. By the end of each lesson, I knew what I was supposed to do during the week. The class felt relaxed enough to ask questions without overthinking it. Thanks to everyone who supported me.
Astrid Kral
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. Lesson times could fit around school, university or work. Once I understood the reasons behind the facts, the questions felt less random. My tutor made it easy to ask questions from the first lesson. My tutor could see my reasoning and usually found the source of an error quickly. It was an intense period, but it was worth it.
