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!

When I started preparing for IB Diploma, I wasn't sure what order to study things in. One bad mock no longer made me want to drop the whole plan. Practicing in the real exam format made test day feel much less unfamiliar. Thanks to TestPrep for helping me stay on track.

I was taking IB Mathematics AI at school, but getting used to the exam questions took time. I finally understood what was going wrong in IB Mathematics AI. I stopped doing a huge amount one week and nothing the next. I started seeing shorter solutions that were easier to check under time pressure. I left the exam feeling that I had done what I could. Thank you to my tutor and the TestPrep team.

I chose IB Visual Arts this year and wanted to build a solid base from the beginning. A big thank you to my tutor for all the support :)

I was close to my target, but my results changed a lot from one test to the next. Lesson times could fit around school, university or work. Once I understood the reasons behind the facts, the questions felt less random. My tutor made it easy to ask questions from the first lesson. My tutor could see my reasoning and usually found the source of an error quickly. It was an intense period, but it was worth it.

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.

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.

What annoyed me most was losing easy points because I rushed. We were realistic about what could be improved in the time available. Source questions became easier once I noticed how small details affected the mark. My tutor made it easy to ask questions from the first lesson. A clear plan for the final weeks made priorities much easier to see. It was an intense period, but it was worth it.

Over time, IB Philosophy became one of the most organized parts of my IB Diploma preparation. I stopped listing facts in essays and started building an actual argument. I became much more comfortable asking questions in class.

The IB Diploma format felt unnecessarily confusing at first. I'm genuinely thankful to my tutor for being patient.
Catalina Tellez
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. Near the exam, it was clear what to keep doing and what to stop. Lesson times could fit around school, university or work. A quick check after each answer helped me catch small mistakes. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.
Greta Thiele
- IB Diploma
The feedback I received on IB World History was clear and practical. Going back to the lesson recordings helped when I forgot a small step. Using the mark scheme to review my own answer was surprisingly helpful. I wasn't trying to learn new topics at the very last minute. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

Our son's school schedule was already very busy. A good connection with the tutor developed quite quickly. Being able to fit lessons around school made the process easier. Joining lessons willingly was one of the clearest signs for us. Flexible scheduling helped during a demanding school year. We would recommend the program to students and families in a similar situation.
