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 wanted our child to keep up with the school pace in IB Physics. The class size kept our child from disappearing into the background. We were able to follow the mock results regularly. Online lessons made it possible to continue without losing time on travel. We thank the tutor and the TestPrep team.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor usually asked me to explain my thinking before stepping in. After each test, we looked beyond the score and reviewed the type of each mistake. The lessons where I found the bug myself were the ones I remembered best. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.

It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. We quickly felt that the tutor was a good match.

- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. Having the lesson move at my pace made the process feel much easier. My written code answers became much more organized. The plan changed with my mock and homework results, so the work never felt random. Lesson times could fit around school, university or work. Thank you to the tutor who stayed supportive until the end.

We didn't spend extra time on things I already knew. I finally understood what was going wrong in IB Chemistry. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.

We wanted our child to keep up with the school pace in Theory of Knowledge (TOK). The tutor's close attention to weaker areas gave us confidence. The lessons started being followed without constant reminders from us. The tutor supported regular study, not only the lesson content. Seeing the change in our child made us very happy.

I finally understood what was going wrong in IB Economics. We could make the workload lighter during busy weeks at school or university. I learned to separate the information needed for a decision from the extra detail. There was no overnight miracle, but the progress was easy to see. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.
Joel Warren
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. One bad mock no longer made me want to drop the whole plan. Experiencing the exam format beforehand made test day much less stressful. Practicing in the real exam format made test day feel much less unfamiliar. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.

Keeping school units and exam preparation in the same plan worked really well. The feedback I received on IB Business Management was clear and practical. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.
Ishita Joshi
- IB Diploma
Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I learned to make a short plan before starting a long response. There was no overnight miracle, but the progress was easy to see. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.

Breaking IB Chemistry into smaller pieces worked much better for me. Separating calculation errors from content gaps made revision more useful. After a while, the questions started to feel much more familiar.

What annoyed me most was losing easy points because I rushed. It was an intense period, but it was worth it.
Ananya Bedi
- IB Diploma
I chose IB English A this year and wanted to build a solid base from the beginning. We could make the workload lighter during busy weeks at school or university. A lot of my mistakes came from rushing through the wording of the question. A big thank you to my tutor for all the support :)

Everyone recommended different resources and I kept switching between them. The class felt relaxed enough to ask questions without overthinking it. Past-paper questions showed me how different topics could appear together. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. I was really happy with the lessons.
Liam Ingram
- IB Diploma
The feedback I received on IB Philosophy was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.
Oscar Sutherland

Full-length mocks helped me get used to the real exam pace. Over time, Internal Assessment (IA) became one of the most organized parts of my IB Diploma preparation. After a while, the questions started to feel much more familiar. I was really happy with the lessons.
Nina Meier
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. I used the question bank regularly to return to weaker topics. Using the mark scheme to review my own answer was surprisingly helpful. Going back to the lesson recordings helped when I forgot a small step. I was really happy with the lessons.
