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!

When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. I started seeing shorter solutions that were easier to check under time pressure. The preparation felt calmer than I expected.

I was doing questions for IGCSE Physics on my own but never had a steady routine. After enough examples of the same question type, the repeated mistakes decreased. My confidence improved along with the results. It was an intense period, but it was worth it.

Our son's school schedule was already very busy. We were able to follow the mock results regularly. Joining lessons willingly was one of the clearest signs for us. Full-length tests showed how time was being used across the exam. A good connection with the tutor developed quite quickly. We would recommend the program to students and families in a similar situation.

Over time, IGCSE English as a Second Language became one of the most organized parts of my IGCSE / GCSE preparation. I started tracking the type of mistake, not just the number of questions I completed. I learned not to spend the same amount of time on every line of a long text. I became much more comfortable asking questions in class. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. Knowing what to study reduced a lot of the stress.

Over time, IGCSE Combined Science became one of the most organized parts of my IGCSE / GCSE preparation. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. My confidence improved along with the results.
Jisung Moon
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Timed work showed exactly which section was slowing me down. Thanks to TestPrep for helping me stay on track.

The lessons started being followed without constant reminders from us. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.

Past-paper questions showed me how different topics could appear together. The preparation felt calmer than I expected.

- IGCSE / GCSE
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I wasn't trying to learn new topics at the very last minute.

Keeping up with IGCSE / GCSE while school was busy was harder than I expected. I was really happy with the lessons.
Maelle Girard
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

At the beginning, we knew very little about the IGCSE / GCSE system as parents. Flexible scheduling helped during a demanding school year.

I started seeing shorter solutions that were easier to check under time pressure. Thank you to my tutor and the TestPrep team.

Breaking IGCSE English as a Second Language into smaller pieces worked much better for me. A lot of my mistakes came from rushing through the wording of the question. My preparation became much more regular and easier to track.
Elisa Fiore
- IGCSE / GCSE
I chose IGCSE Mathematics this year and wanted to build a solid base from the beginning. Breaking IGCSE Mathematics into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. Seeing several versions of the same topic made unfamiliar questions less stressful. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.

I finally understood what was going wrong in IGCSE Additional Mathematics. A quick check after each answer helped me catch small mistakes. There was no overnight miracle, but the progress was easy to see.
