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 been studying alone, but my results stopped improving after a point. I found a better balance between regular school and exam preparation.
Bo Xiao
- 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. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.
Riya Ghosh
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. I found a better balance between regular school and exam preparation.
Arda Uzun
- AP Exams
Having the lesson move at my pace made the process feel much easier. Over time, AP Microeconomics became one of the most organized parts of my AP Exams preparation. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

Breaking ACT English into smaller pieces worked much better for me. I found a better balance between regular school and exam preparation.
Erik Dudek
- AP Exams
The feedback I received on AP Physics C: E&M was clear and practical. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. I left the exam feeling that I had done what I could. I went into the exam much calmer than I would have before. I was really happy with the lessons.
Eunji Jin
- PTE Academic
I chose Write from Dictation 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. I learned not to lose the rest of a listening task because I missed one word. A big thank you to my tutor for all the support :)
Siddharth Arora
- Digital SAT
Anxiety became more visible as the exam got closer. Joining lessons willingly was one of the clearest signs for us. Being able to fit lessons around school made the process easier. It was good to see confidence returning over time. Communication with the team was straightforward and our questions were answered. Thank you sincerely to everyone involved.
Trang Truong
- IGCSE / GCSE
I was doing questions for IGCSE Biology on my own but never had a steady routine. I went into the exam much calmer than I would have before.
Renata Loyola

Our daughter needed regular support with ACT English. The tutor's close attention to weaker areas gave us confidence. We were pleased with the support we received.
Vikram Gill
- IB Diploma
I worked on keeping a steady pace instead of rushing the easy questions. The preparation felt calmer than I expected.
Cassidy Raines
- Digital SAT
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. We were realistic about what could be improved in the time available. I can now decide much faster when to move on from a question. My preparation became much more regular and easier to track. Thanks to TestPrep for helping me stay on track.
Emi Sakamoto

We wanted our child to keep up with the school pace in AP Physics C: Mechanics. We quickly felt that the tutor was a good match.
Nikhil Sharma

Breaking AP US History into smaller pieces worked much better for me. Source questions became easier once I noticed how small details affected the mark. I started noticing the reason for a mistake much faster.
Chelsea Dwyer
- A-Level
I was close to my target, but my results changed a lot from one test to the next. The group never had more than six students, so it was easy to stay involved. There was no overnight miracle, but the progress was easy to see. Thank you to my tutor and the TestPrep team.
Brooklyn Chapman
- IB Diploma
Our child wasn't sure how to organize the preparation for IB Diploma. The tutor's close attention to weaker areas gave us confidence. Online lessons made it possible to continue without losing time on travel. It was good to see confidence returning over time. We were happy with both the teaching and the communication.

Seeing several versions of the same topic made unfamiliar questions less stressful. I was really happy with the lessons.

Ginevra Ferri
- IB Diploma
I was doing questions for IB Visual Arts on my own but never had a steady routine. Near the exam, it was clear what to keep doing and what to stop. Even in a group lesson, the tutor knew where each of us stood. Reviewing my work against the criteria changed the way I edited it. After a while, the questions started to feel much more familiar. Thanks to everyone who supported me.
