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 finally understood what was going wrong in AP World History. Connecting examples back to the main point made my writing more consistent. I started noticing the reason for a mistake much faster.

Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. Online lessons made it possible to continue without losing time on travel. Topic-based question practice made study time more focused. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.

As the exam got closer, I wasn't sure what I should actually review. Over time, AP Human Geography became one of the most organized parts of my AP Exams preparation. The plan changed with my mock and homework results, so the work never felt random. I stopped listing facts in essays and started building an actual argument. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

Over time, AP Physics C: E&M became one of the most organized parts of my AP Exams preparation. I stopped doing a huge amount one week and nothing the next. Past-paper questions showed me how different topics could appear together. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.

I chose AP Computer Science Principles this year and wanted to build a solid base from the beginning. I wasn't trying to learn new topics at the very last minute.

I was doing questions for AP Human Geography on my own but never had a steady routine. I became much more comfortable asking questions in class.
Aline Nunes

After my first attempt, I wanted the second round of preparation to feel more organized. I finally understood what was going wrong in AP Comparative Government. The plan changed with my mock and homework results, so the work never felt random. Using the mark scheme to review my own answer was surprisingly helpful. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.

Andre Moura

What annoyed me most was losing easy points because I rushed. One bad mock no longer made me want to drop the whole plan. Choosing questions by topic made my practice time much more useful. Breaking the draft into smaller parts made it feel much more doable. My preparation became much more regular and easier to track. I'm genuinely thankful to my tutor for being patient.

Signe Sorensen

The AP Exams format felt unnecessarily confusing at first. I stopped doing a huge amount one week and nothing the next. I became much more careful with graphs, experiments and data-based questions. I was really happy with the lessons.
Linnea Dudek

Once I understood the reasons behind the facts, the questions felt less random. It was an intense period, but it was worth it.
Bryce Mallory
- AP Exams
I chose AP US History this year and wanted to build a solid base from the beginning. We could make the workload lighter during busy weeks at school or university. I learned to make a short plan before starting a long response. I was really happy with the lessons.
Vasco Antunes
- AP Exams
Everyone recommended different resources and I kept switching between them. One bad mock no longer made me want to drop the whole plan. A clear plan for the final weeks made priorities much easier to see. Using the mark scheme to review my own answer was surprisingly helpful. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.
