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!

The feedback I received on Algebra was clear and practical. 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. My confidence improved along with the results. Knowing what to study reduced a lot of the stress. Thank you to the tutor who stayed supportive until the end.

Anxiety became more visible as the exam got closer. The tutor supported regular study, not only the lesson content.
Shelby Dalton
- IMAT
When I started preparing for IMAT, I wasn't sure what order to study things in. Having the lesson move at my pace made the process feel much easier. I learned to make a short plan before starting a long response. My tutor usually asked me to explain my thinking before stepping in. I'm glad I worked with my tutor through this process.
Ana Oliveira
- IGCSE / GCSE
Flexible scheduling helped during a demanding school year. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Andres Trevino
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. I'm genuinely thankful to my tutor for being patient.

- AP Exams
I chose AP Art History this year and wanted to build a solid base from the beginning. I'm glad I worked with my tutor through this process.
Andre Moura
- PTE Academic
The feedback I received on Reading was clear and practical. I found a better balance between regular school and exam preparation.
Renata Escobar
- GMAT Focus
I knew my target, but I didn't have a realistic routine for GMAT Focus. The plan changed with my mock and homework results, so the work never felt random. Separating strategy mistakes from content gaps made progress much quicker. The preparation felt calmer than I expected.
Reid Ramsey
- IGCSE / GCSE
We noticed that the resources kept changing during independent study. Full-length tests showed how time was being used across the exam. The plan was adjusted when school exams became busy. The tutor supported regular study, not only the lesson content. The overall experience was positive from beginning to end.
Angus Aldridge
- ACT
The class felt relaxed enough to ask questions without overthinking it. Over time, Time Management became one of the most organized parts of my ACT preparation. My preparation became much more regular and easier to track. I was really happy with the lessons.
Edoardo Bernardi
- Digital SAT
I can now decide much faster when to move on from a question. A big thank you to my tutor for all the support :)
Nari Kim
- A-Level
After the first attempt, we looked for a calmer plan for the retake. A realistic plan for the final weeks reduced stress for the whole family. A good connection with the tutor developed quite quickly. We were able to follow the mock results regularly. Seeing the change in our child made us very happy.
Ilse Kruger
- SSAT
I chose Reading this year and wanted to build a solid base from the beginning. Lesson times could fit around school, university or work. I stopped choosing answers by feel and started looking for evidence in the passage. I started tracking the type of mistake, not just the number of questions I completed. Thanks to TestPrep for helping me stay on track.
Eylul Polat
- AP Exams
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.
Ana Cunha
- AP Exams
Over time, AP US Government became one of the most organized parts of my AP Exams preparation. My preparation became much more regular and easier to track.
Signe Sorensen
- AP Exams
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
- PTE Academic
I came back to Write from Dictation after a long break and wasn't sure where to begin. It was an intense period, but it was worth it.
Oliver Sweeney
- GMAT Focus
Breaking Data Insights 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. A quick check after each answer helped me catch small mistakes. I wasn't trying to learn new topics at the very last minute. I went into the exam much calmer than I would have before. I was really happy with the lessons.
Avni Malhotra
- IMAT
Lesson times could fit around school, university or work. Over time, General Knowledge became one of the most organized parts of my IMAT preparation. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.
Yuna Tanaka
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. Having the lesson move at my pace made the process feel much easier. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.
Claire Picard
- YÖS / TR-YÖS
As the exam got closer, I wasn't sure what I should actually review. I became much more comfortable asking questions in class.
Harrison Ritchie
- IELTS Academic
Everyone recommended different resources and I kept switching between them. I left the exam feeling that I had done what I could.
Doyun Kang
- A-Level
Our child had a clear goal but no steady study routine. The lessons started being followed without constant reminders from us.
Tegan Quade
- AP Exams
Once I understood the reasons behind the facts, the questions felt less random. It was an intense period, but it was worth it.
