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 was doing questions for AP European History on my own but never had a steady routine. The feedback I received on AP European History was clear and practical. I never felt awkward asking the same thing again. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.

At the beginning, we knew very little about the AP Exams system as parents. The tutor's close attention to weaker areas gave us confidence. We were happy with both the teaching and the communication.

Breaking AP World History into smaller pieces worked much better for me. My mock results gradually became more consistent.

When I started preparing for AP Exams, I wasn't sure what order to study things in. Near the exam, it was clear what to keep doing and what to stop. With data-heavy questions, I began reading the task before getting lost in the table. Thanks to everyone who supported me.

The mocks showed where my time was actually being lost. The feedback I received on AP Macroeconomics was clear and practical. After a while, the questions started to feel much more familiar. A big thank you to my tutor for all the support :)

I was close to my target, but my results changed a lot from one test to the next. Going back to the lesson recordings helped when I forgot a small step. Separating calculation errors from content gaps made revision more useful. Thank you to the tutor who stayed supportive until the end.

Keeping up with AP Exams while school was busy was harder than I expected. After enough examples of the same question type, the repeated mistakes decreased. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.

After my first attempt, I wanted the second round of preparation to feel more organized. Even in a group lesson, the tutor knew where each of us stood. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

I was taking AP English Language at school, but getting used to the exam questions took time. Breaking AP English Language into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. My written answers became shorter, clearer and easier to follow. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.

The AP Exams format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. Learning when to leave a hard question made a real difference to my timing. We could make the workload lighter during busy weeks at school or university. Having the lesson move at my pace made the process feel much easier. It was an intense period, but it was worth it.

I finally understood what was going wrong in AP Psychology. I started tracking the type of mistake, not just the number of questions I completed. I stopped listing facts in essays and started building an actual argument. My confidence improved along with the results. I found a better balance between regular school and exam preparation. A big thank you to my tutor for all the support :)

Everyone recommended different resources and I kept switching between them. Going back to the lesson recordings helped when I forgot a small step. I became much more careful with graphs, experiments and data-based questions. Thank you to my tutor and the TestPrep team.

I finally understood what was going wrong in AP Chemistry. The plan changed with my mock and homework results, so the work never felt random. Separating calculation errors from content gaps made revision more useful. Knowing what to study reduced a lot of the stress. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

The tutor supported regular study, not only the lesson content. We would recommend the program to students and families in a similar situation.

The feedback I received on AP Research was clear and practical. One bad mock no longer made me want to drop the whole plan. Breaking the draft into smaller parts made it feel much more doable. I started noticing the reason for a mistake much faster. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
