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!

We noticed that the resources kept changing during independent study. 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 English B. Discussing why the other choices were wrong helped more than I expected. Knowing what to study reduced a lot of the stress.

I was taking IB Global Politics at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. I stopped listing facts in essays and started building an actual argument. I was really happy with the lessons.

Over time, IB Mathematics AI became one of the most organized parts of my IB Diploma preparation. There was no overnight miracle, but the progress was easy to see.

When I started preparing for IB Diploma, I wasn't sure what order to study things in. After each test, we looked beyond the score and reviewed the type of each mistake. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.

Keeping up with IB Diploma while school was busy was harder than I expected. Having the lesson move at my pace made the process feel much easier. Practicing in the real exam format made test day feel much less unfamiliar. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. Thank you to the tutor who stayed supportive until the end.

When I started preparing for IB Diploma, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

Our son's school schedule was already very busy. Mistakes became something to work on rather than something to feel bad about. Communication with the team was straightforward and our questions were answered. Full-length tests showed how time was being used across the exam. The plan was adjusted when school exams became busy. Thank you sincerely to everyone involved.

I was doing questions for IB Physics on my own but never had a steady routine. The plan changed with my mock and homework results, so the work never felt random. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thank you to my tutor and the TestPrep team.

I finally understood what was going wrong in IB Mathematics AA. Going back to the lesson recordings helped when I forgot a small step. We focused more on understanding what the problem asked than memorizing formulas. After a while, the questions started to feel much more familiar. My preparation became much more regular and easier to track. Thank you to the tutor who stayed supportive until the end.

The feedback I received on IB Mathematics AA was clear and practical. Near the exam, it was clear what to keep doing and what to stop. A quick check after each answer helped me catch small mistakes. I went into the exam much calmer than I would have before. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

Everyone recommended different resources and I kept switching between them. I wasn't trying to learn new topics at the very last minute.

I was taking Theory of Knowledge (TOK) at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. We were realistic about what could be improved in the time available. The feedback helped me improve my own work without writing it for me. I left the exam feeling that I had done what I could. Thanks to TestPrep for helping me stay on track.
