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!

Anxiety became more visible as the exam got closer. The tutor's close attention to weaker areas gave us confidence. Seeing the change in our child made us very happy.

I finally understood what was going wrong in IB Biology. I never felt awkward asking the same thing again. Separating calculation errors from content gaps made revision more useful. There was no overnight miracle, but the progress was easy to see. My mock results gradually became more consistent. Thanks to everyone who supported me.

The IB Diploma format felt unnecessarily confusing at first. The feedback I received on IB Philosophy was clear and practical. The plan changed with my mock and homework results, so the work never felt random. Source questions became easier once I noticed how small details affected the mark. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.

What annoyed me most was losing easy points because I rushed. I started tracking the type of mistake, not just the number of questions I completed. Connecting examples back to the main point made my writing more consistent. Thank you to my tutor and the TestPrep team.

We noticed that the resources kept changing during independent study. It was good to see confidence returning over time. Individual lesson time was used around our child's actual needs. Preparation looked calmer and more organized closer to the exam. We were able to follow the mock results regularly. We quickly felt that the tutor was a good match.

The feedback I received on IB English B was clear and practical. Going back to the lesson recordings helped when I forgot a small step. My written answers became shorter, clearer and easier to follow. I wasn't trying to learn new topics at the very last minute. My mock results gradually became more consistent. The preparation felt calmer than I expected.

I finally understood what was going wrong in IB TITC. Near the exam, it was clear what to keep doing and what to stop. I worked on keeping a steady pace instead of rushing the easy questions. My confidence improved along with the results. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.

After the first attempt, we looked for a calmer plan for the retake. Communication with the team was straightforward and our questions were answered. Returning to actual gaps instead of restarting everything saved time. A good connection with the tutor developed quite quickly. Mistakes became something to work on rather than something to feel bad about. Seeing the change in our child made us very happy.

Breaking IB Chemistry into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week.

Thanks to TestPrep for helping me stay on track.

As the exam got closer, I wasn't sure what I should actually review. I finally understood what was going wrong in IB ESS. We could make the workload lighter during busy weeks at school or university. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.

Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thank you to the tutor who stayed supportive until the end.

I was taking Theory of Knowledge (TOK) at school, but getting used to the exam questions took time. I finally understood what was going wrong in Theory of Knowledge (TOK).

Kunal Sethi
- IB Diploma
I was doing questions for Theory of Knowledge (TOK) on my own but never had a steady routine. After each test, we looked beyond the score and reviewed the type of each mistake. I realized that choosing a topic, researching and revising each needed its own deadline. The plan changed with my mock and homework results, so the work never felt random. It was an intense period, but it was worth it.
Kabir Sethi

The class felt relaxed enough to ask questions without overthinking it. Breaking IB Business Management into smaller pieces worked much better for me. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
