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!

Lesson times could fit around school, university or work. Breaking IB Mathematics AI into smaller pieces worked much better for me. My preparation became much more regular and easier to track. Thanks to TestPrep for helping me stay on track.

Reagan Ramsey
- IMAT
I chose Mathematics this year and wanted to build a solid base from the beginning. We didn't spend extra time on things I already knew. Learning when to leave a hard question made a real difference to my timing. One bad mock no longer made me want to drop the whole plan. I'm glad I worked with my tutor through this process.
Jingyi Sun
- SSAT
I was doing questions for Upper Level on my own but never had a steady routine. Breaking Upper Level into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. 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. Thanks to everyone who supported me.

We wanted our child to keep up with the school pace in IB Physics. Individual lesson time was used around our child's actual needs. We quickly felt that the tutor was a good match.

Our son's school schedule was already very busy. Being able to fit lessons around school made the process easier. Thank you sincerely to everyone involved.

- GRE General
I came back to Data Analysis after a long break and wasn't sure where to begin. Breaking Data Analysis 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. I found a better balance between regular school and exam preparation. Thanks to everyone who supported me.

Julian Saavedra
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. I finally understood what was going wrong in A-Level Chemistry. My tutor made it easy to ask questions from the first lesson. Separating calculation errors from content gaps made revision more useful. I went into the exam much calmer than I would have before. The preparation felt calmer than I expected.

Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. Online lessons made it possible to continue without losing time on travel. Topic-based question practice made study time more focused. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.

We weren't sure whether online lessons would be effective. The plan was adjusted when school exams became busy. Being able to fit lessons around school made the process easier.

As the exam got closer, I wasn't sure what I should actually review. The feedback I received on Geometry was clear and practical.

Thanks to everyone who supported me.

- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. We didn't spend extra time on things I already knew. I understood that the portfolio needed to show the process, not only the finished piece. Near the exam, it was clear what to keep doing and what to stop. My tutor could see my reasoning and usually found the source of an error quickly. I'm genuinely thankful to my tutor for being patient.
