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 had collected too many resources without knowing when to use any of them. Breaking Verbal Reasoning into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. My written answers became shorter, clearer and easier to follow. I became much more comfortable asking questions in class. I'm glad I worked with my tutor through this process.

In Data Sufficiency, timing was costing me more points than the content itself. I finally understood what was going wrong in Data Sufficiency. I stopped doing a huge amount one week and nothing the next. Separating strategy mistakes from content gaps made progress much quicker. I wasn't trying to learn new topics at the very last minute. I was really happy with the lessons.

I came back to Data Sufficiency after a long break and wasn't sure where to begin. The group never had more than six students, so it was easy to stay involved. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.

After my first attempt, I wanted a calmer and more focused plan for the retake. Breaking Data Insights into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I started seeing shorter solutions that were easier to check under time pressure. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.

The feedback I received on Quantitative Reasoning was clear and practical. One bad mock no longer made me want to drop the whole plan. Learning when to leave a hard question made a real difference to my timing. My mock results gradually became more consistent. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

My mock scores were inconsistent, so it was hard to judge my actual level. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. A quick check after each answer helped me catch small mistakes. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.

With data-heavy questions, I began reading the task before getting lost in the table. I'm glad I worked with my tutor through this process.

Balancing GMAT Focus preparation with university and work was harder than I expected. I started tracking the type of mistake, not just the number of questions I completed. Focusing on past papers and mock review worked well near the exam. Seeing several versions of the same topic made unfamiliar questions less stressful. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

I had been studying alone, but my results stopped improving after a point. Breaking Data Sufficiency into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. Balancing Quant and Verbal in the same week worked better than studying them in blocks. My mock results gradually became more consistent. Thank you to my tutor and the TestPrep team.
