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 had collected too many resources without knowing when to use any of them. One bad mock no longer made me want to drop the whole plan. Discussing why the other choices were wrong helped more than I expected. I'm glad I worked with my tutor through this process.
Duy Le
- Digital SAT
Over time, Reading & Writing became one of the most organized parts of my Digital SAT preparation. Discussing why the other choices were wrong helped more than I expected. My mock results gradually became more consistent.
Lea Renard
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. Breaking AP Calculus BC into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. I started seeing shorter solutions that were easier to check under time pressure. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.
Carolina Marques
- AP Exams
The feedback I received on AP English Language was clear and practical. My tutor made it easy to ask questions from the first lesson. I stopped choosing answers by feel and started looking for evidence in the passage. My confidence improved along with the results. I started noticing the reason for a mistake much faster. I was really happy with the lessons.
Nathan Underwood
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. I left the exam feeling that I had done what I could.
Nuria Simoes
- TOEFL iBT
Breaking Speaking into smaller pieces worked much better for me. I developed a clearer way to return to the text during reading questions. My mock results gradually became more consistent.
Zoe Rafferty
- GRE General
I had collected too many resources without knowing when to use any of them. I became much more comfortable asking questions in class.
Lucy Palmer
- YÖS / TR-YÖS
The YÖS / TR-YÖS format felt unnecessarily confusing at first. My confidence improved along with the results.
Hina Maeda

I was taking Reading at school, but getting used to the exam questions took time. Thank you to my tutor and the TestPrep team.
Brodie Redfern
- GRE General
Over time, Section-Adaptive Strategy became one of the most organized parts of my GRE General preparation. My mock results gradually became more consistent.
Darcy Whitlam
- Digital SAT
We noticed that the resources kept changing during independent study. Preparation looked calmer and more organized closer to the exam. The tutor supported regular study, not only the lesson content. Regular mocks built familiarity with the real exam pace. The overall experience was positive from beginning to end.
Joel McIntyre
- IMAT
I finally understood what was going wrong in Physics. We could make the workload lighter during busy weeks at school or university. I became much more careful with graphs, experiments and data-based questions. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Nari Yang
- IB Diploma
Over time, IB Turkish A became one of the most organized parts of my IB Diploma preparation. I never felt awkward asking the same thing again. I worked on keeping a steady pace instead of rushing the easy questions. There was no overnight miracle, but the progress was easy to see. I went into the exam much calmer than I would have before. A big thank you to my tutor for all the support :)
Kavya Tandon
- IGCSE / GCSE
The feedback I received on IGCSE Additional Mathematics was clear and practical. I started tracking the type of mistake, not just the number of questions I completed. Seeing several versions of the same topic made unfamiliar questions less stressful. I wasn't trying to learn new topics at the very last minute. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.
Jakub Moen
- AP Exams
At the beginning, we knew very little about the AP Exams system as parents. Online lessons made it possible to continue without losing time on travel.
Sora Sung
- IB Diploma
Joining lessons willingly was one of the clearest signs for us. It was good to see confidence returning over time. Seeing the change in our child made us very happy.
Petra Kaczmarek
- ACT
Our child had a clear goal but no steady study routine. Mistakes became something to work on rather than something to feel bad about. We were able to follow the mock results regularly. A realistic plan for the final weeks reduced stress for the whole family. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.
Sienna Lindley
- AP Exams
I chose AP Chemistry this year and wanted to build a solid base from the beginning. My tutor usually asked me to explain my thinking before stepping in. Past-paper questions showed me how different topics could appear together. Thanks to TestPrep for helping me stay on track.
Bruna Campos
- IGCSE / GCSE
Over time, IGCSE Mathematics became one of the most organized parts of my IGCSE / GCSE preparation. The plan changed with my mock and homework results, so the work never felt random. Seeing several versions of the same topic made unfamiliar questions less stressful. There was no overnight miracle, but the progress was easy to see. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Tolga Bilgin
- IGCSE / GCSE
The feedback I received on IGCSE Geography was clear and practical. I never felt awkward asking the same thing again. Source questions became easier once I noticed how small details affected the mark. I started noticing the reason for a mistake much faster. My confidence improved along with the results. Thank you to the tutor who stayed supportive until the end.

Alessia Caruso
- UCAT
What annoyed me most was losing easy points because I rushed. My tutor usually asked me to explain my thinking before stepping in. Working across different difficulty levels made new questions feel less surprising. I can now decide much faster when to move on from a question. After a while, the questions started to feel much more familiar. A big thank you to my tutor for all the support :)
Rui Chen
- IELTS Academic
Over time, Writing Task 2 became one of the most organized parts of my IELTS Academic preparation. I started tracking the type of mistake, not just the number of questions I completed. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.
