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 finally understood what was going wrong in Text Completion. We could make the workload lighter during busy weeks at school or university. I learned not to spend the same amount of time on every line of a long text. I left the exam feeling that I had done what I could. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.

I finally understood what was going wrong in A-Level Business. My tutor made it easy to ask questions from the first lesson. Separating strategy mistakes from content gaps made progress much quicker. After a while, the questions started to feel much more familiar. Knowing what to study reduced a lot of the stress. A big thank you to my tutor for all the support :)
Finn Ridley
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

- IGCSE / GCSE
The tutor supported regular study, not only the lesson content. We thank the tutor and the TestPrep team.
Parker Sullivan
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. We didn't spend extra time on things I already knew. Past-paper questions showed me how different topics could appear together. I started tracking the type of mistake, not just the number of questions I completed. Having the lesson move at my pace made the process feel much easier. Thank you to my tutor and the TestPrep team.
Carla Lemus

After my first attempt, I wanted the second round of preparation to feel more organized. There was no overnight miracle, but the progress was easy to see.

After my first attempt, I wanted the second round of preparation to feel more organized. I started tracking the type of mistake, not just the number of questions I completed.

Wei Zhou
- A-Level
Breaking A-Level English Literature into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. My written answers became shorter, clearer and easier to follow. There was no overnight miracle, but the progress was easy to see. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.
Neha Pillai
- UCAT
Over time, Verbal Reasoning became one of the most organized parts of my UCAT preparation. I wasn't trying to learn new topics at the very last minute.
Ramon Pascual
- A-Level
At the beginning, we knew very little about the A-Level system as parents. Preparation looked calmer and more organized closer to the exam. A realistic plan for the final weeks reduced stress for the whole family. Joining lessons willingly was one of the clearest signs for us. The lessons started being followed without constant reminders from us. We would recommend the program to students and families in a similar situation.
Renato Correia
- 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. The class size kept our child from disappearing into the background. The lessons started being followed without constant reminders from us. Mistakes became something to work on rather than something to feel bad about. Thank you sincerely to everyone involved.

Aditya Desai
- AP Exams
I chose AP Physics C: E&M this year and wanted to build a solid base from the beginning. Breaking AP Physics C: E&M into smaller pieces worked much better for me. I never felt awkward asking the same thing again. Once I understood the reasons behind the facts, the questions felt less random. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

James Tierney
- AP Exams
I was taking AP English Literature at school, but getting used to the exam questions took time. Breaking AP English Literature into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I learned not to spend the same amount of time on every line of a long text. I went into the exam much calmer than I would have before. Thank you to the tutor who stayed supportive until the end.
