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!

Balancing Quant and Verbal in the same week worked better than studying them in blocks. Thank you to the tutor who stayed supportive until the end.
Mitchell Whelan
- A-Level
Breaking A-Level Chemistry into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. I became much more careful with graphs, experiments and data-based questions. My preparation became much more regular and easier to track. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.
Quentin Aubert
- IGCSE / GCSE
Breaking IGCSE Business Studies into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. Separating strategy mistakes from content gaps made progress much quicker. My mock results gradually became more consistent. Knowing what to study reduced a lot of the stress. I'm genuinely thankful to my tutor for being patient.
Bjorn Lewandowski
- IB Diploma
Our child had a clear goal but no steady study routine. The overall experience was positive from beginning to end.
Lara Callaghan
- IB Diploma
What annoyed me most was losing easy points because I rushed. My tutor made it easy to ask questions from the first lesson. Focusing on past papers and mock review worked well near the exam. Connecting examples back to the main point made my writing more consistent. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.
Minho Yang
- IGCSE / GCSE
The feedback I received on IGCSE Combined Science was clear and practical. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track.
Carmen Cabrera
- Digital SAT
Keeping up with Digital SAT while school was busy was harder than I expected. The preparation felt calmer than I expected.
Darcy Ainsworth
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. The class felt relaxed enough to ask questions without overthinking it. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.
Koray Keskin
- SSAT
Anxiety became more visible as the exam got closer. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.
Ludovica Martinelli
- YÖS / TR-YÖS
The YÖS / TR-YÖS format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. The mocks showed where my time was actually being lost. A quick check after each answer helped me catch small mistakes. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.
Tyler Winslow
- IELTS Academic
I was close to my target, but my results changed a lot from one test to the next. After each test, we looked beyond the score and reviewed the type of each mistake. The writing feedback helped me stop repeating the same sentence-level errors. One bad mock no longer made me want to drop the whole plan. Experiencing the exam format beforehand made test day much less stressful. A big thank you to my tutor for all the support :)
Owen Harmon
- IGCSE / GCSE
We wanted our child to keep up with the school pace in IGCSE Biology. The tutor supported regular study, not only the lesson content. We thank the tutor and the TestPrep team.
Bruna Moraes
- UCAT
Keeping up with UCAT while school was busy was harder than I expected. Over time, Quantitative Reasoning became one of the most organized parts of my UCAT preparation. By the end of each lesson, I knew what I was supposed to do during the week. I started seeing shorter solutions that were easier to check under time pressure. I wasn't trying to learn new topics at the very last minute. The preparation felt calmer than I expected.
Rodrigo Montoya
- AP Exams
What annoyed me most was losing easy points because I rushed. The plan changed with my mock and homework results, so the work never felt random. The mocks showed where my time was actually being lost. Using the mark scheme to review my own answer was surprisingly helpful. I wasn't trying to learn new topics at the very last minute. Thanks to TestPrep for helping me stay on track.
Noelia Aguirre
- UCAT
I was doing questions for Quantitative Reasoning on my own but never had a steady routine. Even in a group lesson, the tutor knew where each of us stood. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.
Itsuki Ota
- SSAT
I finally understood what was going wrong in Reading. My written answers became shorter, clearer and easier to follow. I went into the exam much calmer than I would have before.
Valentin Mena
- AP Exams
Our child wasn't sure how to organize the preparation for AP Exams. Preparation looked calmer and more organized closer to the exam.
Danilo Teixeira
- IB Diploma
Knowing the criteria from the start made the whole task less vague. I'm genuinely thankful to my tutor for being patient.
Lucas Marques
- PTE Academic
We didn't spend extra time on things I already knew. Breaking Computer-Based Practice into smaller pieces worked much better for me. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.
Anders Haugen
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. The feedback I received on IB Geography was clear and practical. Going back to the lesson recordings helped when I forgot a small step. Using the mark scheme to review my own answer was surprisingly helpful. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.
Renata Braga
- SSAT
The feedback I received on Elementary Level was clear and practical. I found a better balance between regular school and exam preparation.
Asli Yucel
- IB Diploma
I chose IB Chemistry this year and wanted to build a solid base from the beginning. By the end of each lesson, I knew what I was supposed to do during the week. Once I understood the reasons behind the facts, the questions felt less random. A big thank you to my tutor for all the support :)
Lewis Chandler
- SSAT
At the beginning, we knew very little about the SSAT system as parents. Communication with the team was straightforward and our questions were answered. We were able to follow the mock results regularly. Mock analysis allowed us to follow progress more clearly. The tutor supported regular study, not only the lesson content. We were pleased with the support we received.
Ethan Townsend
- A-Level
Our daughter needed regular support with A-Level History. Communication with the team was straightforward and our questions were answered. Being able to fit lessons around school made the process easier. Preparation looked calmer and more organized closer to the exam. We thank the tutor and the TestPrep team.
