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. I finally understood what was going wrong in IB World History. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Connecting examples back to the main point made my writing more consistent. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

Keeping school units and exam preparation in the same plan worked really well. Over time, IB English B became one of the most organized parts of my IB Diploma preparation. I went into the exam much calmer than I would have before. I was really happy with the lessons.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. 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. Thanks to everyone who supported me.

Lucie Faure

Focusing on past papers and mock review worked well near the exam. Breaking IB Biology into smaller pieces worked much better for me. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)
Marta Cunha
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. One bad mock no longer made me want to drop the whole plan. Focusing on past papers and mock review worked well near the exam. Separating strategy mistakes from content gaps made progress much quicker. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

Everyone recommended different resources and I kept switching between them. Thanks to everyone who supported me.
Brooke Franklin

When I started preparing for IB Diploma, I wasn't sure what order to study things in. My tutor could see my reasoning and usually found the source of an error quickly. I became much more comfortable asking questions in class. I was really happy with the lessons.

The feedback I received on IB World History was clear and practical. Source questions became easier once I noticed how small details affected the mark. I left the exam feeling that I had done what I could.

Nuria Simoes

Over time, IB Turkish A became one of the most organized parts of my IB Diploma preparation. I never felt awkward asking the same thing again. I worked on keeping a steady pace instead of rushing the easy questions. There was no overnight miracle, but the progress was easy to see. I went into the exam much calmer than I would have before. A big thank you to my tutor for all the support :)

Even in a group lesson, the tutor knew where each of us stood. Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. I left the exam feeling that I had done what I could. Thank you to my tutor and the TestPrep team.
Dewi Hidayat
- IB Diploma
Breaking IB English A into smaller pieces worked much better for me. Near the exam, it was clear what to keep doing and what to stop. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.
Adrian Reyes
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. A clear plan for the final weeks made priorities much easier to see. Breaking the draft into smaller parts made it feel much more doable. My tutor made it easy to ask questions from the first lesson. Focusing on past papers and mock review worked well near the exam. I was really happy with the lessons.
Joonho Ahn
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. We balanced current school topics with past-paper practice. Knowing the criteria from the start made the whole task less vague. I wasn't trying to learn new topics at the very last minute. Thanks to TestPrep for helping me stay on track.
Gabriela Varela
- IB Diploma
I chose IB Physics this year and wanted to build a solid base from the beginning. Full-length mocks helped me get used to the real exam pace. I became much more careful with graphs, experiments and data-based questions. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Experiencing the exam format beforehand made test day much less stressful. Thanks to TestPrep for helping me stay on track.
Davide Testa

Once I understood the reasons behind the facts, the questions felt less random. Thanks to everyone who supported me.
