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!

The feedback I received on AP Statistics was clear and practical. Seeing several versions of the same topic made unfamiliar questions less stressful. I went into the exam much calmer than I would have before.

I chose AP Human Geography this year and wanted to build a solid base from the beginning. Going back to the lesson recordings helped when I forgot a small step. I stopped listing facts in essays and started building an actual argument. Thank you to the tutor who stayed supportive until the end.

I was doing questions for AP European History on my own but never had a steady routine. I used the question bank regularly to return to weaker topics. Connecting examples back to the main point made my writing more consistent. We could make the workload lighter during busy weeks at school or university. Thanks to everyone who supported me.

I was close to my target, but my results changed a lot from one test to the next. Choosing questions by topic made my practice time much more useful. We focused more on understanding what the problem asked than memorizing formulas. I never felt awkward asking the same thing again. The preparation felt calmer than I expected.

Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)

Over time, AP Calculus BC became one of the most organized parts of my AP Exams preparation. Near the exam, it was clear what to keep doing and what to stop. I started seeing shorter solutions that were easier to check under time pressure. After a while, the questions started to feel much more familiar. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.

Breaking AP US History into smaller pieces worked much better for me. Source questions became easier once I noticed how small details affected the mark. I started noticing the reason for a mistake much faster.
