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!

At the beginning, we knew very little about the AP Exams system as parents. A good connection with the tutor developed quite quickly. Flexible scheduling helped during a demanding school year. The tutor's close attention to weaker areas gave us confidence. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.

Over time, AP Statistics became one of the most organized parts of my AP Exams preparation. A quick check after each answer helped me catch small mistakes. My preparation became much more regular and easier to track.

Over time, AP English Language became one of the most organized parts of my AP Exams preparation. I learned not to spend the same amount of time on every line of a long text. My confidence improved along with the results.

As the exam got closer, I wasn't sure what I should actually review. My tutor could see my reasoning and usually found the source of an error quickly. 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. Lesson times could fit around school, university or work. I'm glad I worked with my tutor through this process.

The feedback I received on AP Computer Science A was clear and practical. I never felt awkward asking the same thing again. The lessons where I found the bug myself were the ones I remembered best. I went into the exam much calmer than I would have before. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I started tracking the type of mistake, not just the number of questions I completed. Source questions became easier once I noticed how small details affected the mark. It was an intense period, but it was worth it.

The feedback I received on AP Art History was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. I began using more specific examples when explaining my ideas. I left the exam feeling that I had done what I could. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.

Using the mark scheme to review my own answer was surprisingly helpful. I was really happy with the lessons.
Levi Langford
- AP Exams
I was close to my target, but my results changed a lot from one test to the next. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. 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. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.

I was doing questions for AP English Language on my own but never had a steady routine. We didn't spend extra time on things I already knew. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.

When I started preparing for AP Exams, I wasn't sure what order to study things in. Full-length mocks helped me get used to the real exam pace. Past-paper questions showed me how different topics could appear together. I started tracking the type of mistake, not just the number of questions I completed. It was an intense period, but it was worth it.
