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!

It was good to see confidence returning over time. Preparation looked calmer and more organized closer to the exam. We thank the tutor and the TestPrep team.

The feedback I received on Biology was clear and practical. I started noticing the reason for a mistake much faster.
Hannah Kirkwood
- IGCSE / GCSE
Breaking IGCSE Mathematics into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. A quick check after each answer helped me catch small mistakes. Knowing what to study reduced a lot of the stress. I left the exam feeling that I had done what I could. I'm genuinely thankful to my tutor for being patient.

- SSAT
We wanted our child to keep up with the school pace in Upper Level. Thank you sincerely to everyone involved.
Tahlia Newell
- GMAT Focus
I had collected too many resources without knowing when to use any of them. I'm glad I worked with my tutor through this process.
Maeve Hayes
- Digital SAT
Everyone recommended different resources and I kept switching between them. I never felt awkward asking the same thing again. The group never had more than six students, so it was easy to stay involved. I started seeing shorter solutions that were easier to check under time pressure. I started noticing the reason for a mistake much faster. I'm glad I worked with my tutor through this process.
Valentin Loyola
- SSAT
The SSAT format felt unnecessarily confusing at first. Near the exam, it was clear what to keep doing and what to stop. The mocks showed where my time was actually being lost. I learned not to spend the same amount of time on every line of a long text. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)

I finally understood what was going wrong in Bluebook adaptif modüller. Practicing in the real exam format made test day feel much less unfamiliar. I started noticing the reason for a mistake much faster.

Simone Costa
- AP Exams
Over time, AP Chemistry became one of the most organized parts of my AP Exams preparation. My confidence improved along with the results.
Moritz Smit
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. The feedback I received on AP European History was clear and practical. We could make the workload lighter during busy weeks at school or university. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

- GRE General
I stopped choosing answers by feel and started looking for evidence in the passage. I'm genuinely thankful to my tutor for being patient.

- Digital SAT
Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in Bluebook adaptif modüller. Knowing what to study reduced a lot of the stress. Thank you to the tutor who stayed supportive until the end.

Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. The plan changed with my mock and homework results, so the work never felt random. I stopped listing facts in essays and started building an actual argument. I went into the exam much calmer than I would have before. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

Diya Nair
- Digital SAT
Our daughter needed regular support with Expression of Ideas. Preparation looked calmer and more organized closer to the exam. Joining lessons willingly was one of the clearest signs for us. Topic-based question practice made study time more focused. The tutor supported regular study, not only the lesson content. Seeing the change in our child made us very happy.
Simran Roy
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. I found a better balance between regular school and exam preparation.
Aditi Ahuja
- AP Exams
Everyone recommended different resources and I kept switching between them. By the end of each lesson, I knew what I was supposed to do during the week. Before coding, I began thinking about which structure actually fit the problem. It was an intense period, but it was worth it.
Alba Nieto
- IB Diploma
We noticed that the resources kept changing during independent study. Preparation looked calmer and more organized closer to the exam.

Our son's school schedule was already very busy. Regular mocks built familiarity with the real exam pace. The tutor supported regular study, not only the lesson content. The plan was adjusted when school exams became busy. We thank the tutor and the TestPrep team.
