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 learned to make a short plan before starting a long response. It was an intense period, but it was worth it.

After my first attempt, I wanted the second round of preparation to feel more organized. Thank you to my tutor and the TestPrep team.

The IB Diploma format felt unnecessarily confusing at first. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Before coding, I began thinking about which structure actually fit the problem. The preparation felt calmer than I expected.

We wanted our child to keep up with the school pace in IB Economics. Online lessons made it possible to continue without losing time on travel. The tutor's close attention to weaker areas gave us confidence. We were able to follow the mock results regularly. Flexible scheduling helped during a demanding school year. We would recommend the program to students and families in a similar situation.

What annoyed me most was losing easy points because I rushed. Working across different difficulty levels made new questions feel less surprising. The feedback helped me improve my own work without writing it for me. One bad mock no longer made me want to drop the whole plan. Choosing questions by topic made my practice time much more useful. Thanks to TestPrep for helping me stay on track.

Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. My preparation became much more regular and easier to track.

I finally understood what was going wrong in IB Mathematics AA. We focused more on understanding what the problem asked than memorizing formulas. I started noticing the reason for a mistake much faster.

We wanted our child to keep up with the school pace in IB English B. The plan was adjusted when school exams became busy. Thank you sincerely to everyone involved.

Breaking IB Geography into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. Source questions became easier once I noticed how small details affected the mark. I found a better balance between regular school and exam preparation. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.

Breaking IB Psychology into smaller pieces worked much better for me. I became much more comfortable asking questions in class.
Henrik Markovic
- IB Diploma
We weren't sure whether online lessons would be effective. The lessons started being followed without constant reminders from us. Being able to fit lessons around school made the process easier. We were able to follow the mock results regularly. We quickly felt that the tutor was a good match.

Everyone recommended different resources and I kept switching between them. My tutor usually asked me to explain my thinking before stepping in. Having the lesson move at my pace made the process feel much easier. I can now decide much faster when to move on from a question. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.

At the beginning, we knew very little about the IB Diploma system as parents. Regular work on similar question types reduced repeated mistakes. Joining lessons willingly was one of the clearest signs for us. Online lessons made it possible to continue without losing time on travel. We thank the tutor and the TestPrep team.

I was taking IB ESS at school, but getting used to the exam questions took time. The feedback I received on IB ESS was clear and practical. I started tracking the type of mistake, not just the number of questions I completed. Once I understood the reasons behind the facts, the questions felt less random. After a while, the questions started to feel much more familiar. I'm glad I worked with my tutor through this process.

As the exam got closer, I wasn't sure what I should actually review. I used the question bank regularly to return to weaker topics. I learned to make a short plan before starting a long response. Going back to the lesson recordings helped when I forgot a small step. Choosing questions by topic made my practice time much more useful. I was really happy with the lessons.
Hailey Grady
- IB Diploma
What annoyed me most was losing easy points because I rushed. Going back to the lesson recordings helped when I forgot a small step. Discussing why the other choices were wrong helped more than I expected. A big thank you to my tutor for all the support :)

I chose IB Economics this year and wanted to build a solid base from the beginning. We balanced current school topics with past-paper practice. My confidence improved along with the results. Thank you to my tutor and the TestPrep team.

I was doing questions for IB English B on my own but never had a steady routine. My tutor usually asked me to explain my thinking before stepping in. I learned not to spend the same amount of time on every line of a long text. Thanks to everyone who supported me.
Remi Perrin
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. We didn't spend extra time on things I already knew. Seeing several versions of the same topic made unfamiliar questions less stressful. Going back to the lesson recordings helped when I forgot a small step. Thanks to everyone who supported me.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor made it easy to ask questions from the first lesson. We focused more on understanding what the problem asked than memorizing formulas. Thank you to my tutor and the TestPrep team.

Even in a group lesson, the tutor knew where each of us stood. Breaking IB World History into smaller pieces worked much better for me. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.

The plan was adjusted when school exams became busy. Seeing the change in our child made us very happy.
