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!

- UCAT
When I started preparing for UCAT, I wasn't sure what order to study things in. Breaking Time Management into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. Sorting mistakes after each mock changed the way I studied. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.
Henrique Ramos
- LSAT
I stopped choosing answers by feel and started looking for evidence in the passage. It was an intense period, but it was worth it.
Valentina Ocampo
- IGCSE / GCSE
I was doing questions for IGCSE English Literature on my own but never had a steady routine. Full-length mocks helped me get used to the real exam pace. I learned not to spend the same amount of time on every line of a long text. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. The mocks showed where my time was actually being lost. I'm glad I worked with my tutor through this process.
Parker Mercer
- ACT
Seeing several versions of the same topic made unfamiliar questions less stressful. It was an intense period, but it was worth it.
Minseok Pyo
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. My case responses became more organized and direct. Thanks to TestPrep for helping me stay on track.
Miguel Valdez
- GRE General
The feedback I received on Section-Adaptive Strategy was clear and practical. I started noticing the reason for a mistake much faster.
Oscar Murray
- YÖS / TR-YÖS
We focused more on understanding what the problem asked than memorizing formulas. I'm glad I worked with my tutor through this process.
Alice Redmond
- PTE Academic
Joining lessons willingly was one of the clearest signs for us. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.
Arianna Palmieri
- PTE Academic
Our child wasn't sure how to organize the preparation for PTE Academic. Preparation looked calmer and more organized closer to the exam. Mistakes became something to work on rather than something to feel bad about. Being able to fit lessons around school made the process easier. The lessons started being followed without constant reminders from us. We quickly felt that the tutor was a good match.
Callum Webster
- IB Diploma
I chose IB World History this year and wanted to build a solid base from the beginning. Keeping school units and exam preparation in the same plan worked really well. I went into the exam much calmer than I would have before. The preparation felt calmer than I expected.
Kenta Maeda
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. Going back to the lesson recordings helped when I forgot a small step. I learned not to spend the same amount of time on every line of a long text. Thanks to TestPrep for helping me stay on track.
Lara Lambert
- A-Level
After my first attempt, I wanted the second round of preparation to feel more organized. I never felt awkward asking the same thing again. Past-paper questions showed me how different topics could appear together. A big thank you to my tutor for all the support :)

Anxiety became more visible as the exam got closer. Regular mocks built familiarity with the real exam pace. The overall experience was positive from beginning to end.
Sari Hartono
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Working across different difficulty levels made new questions feel less surprising. A quick check after each answer helped me catch small mistakes. My tutor made it easy to ask questions from the first lesson. After enough examples of the same question type, the repeated mistakes decreased. The preparation felt calmer than I expected.
Pippa Ritchie
- Digital SAT
I was doing questions for Problem Solving & Data Analysis on my own but never had a steady routine. My tutor could see my reasoning and usually found the source of an error quickly. I found a better balance between regular school and exam preparation. The preparation felt calmer than I expected.
Skye Jenkins
- Digital SAT
I was doing questions for Geometry & Trigonometry on my own but never had a steady routine. My tutor could see my reasoning and usually found the source of an error quickly. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.
Joris Busch
- IB Diploma
Focusing on past papers and mock review worked well near the exam. Over time, Internal Assessment (IA) became one of the most organized parts of my IB Diploma preparation. Knowing what to study reduced a lot of the stress. I'm glad I worked with my tutor through this process.
Rasmus Ahlberg
- A-Level
Connecting examples back to the main point made my writing more consistent. I'm glad I worked with my tutor through this process.

Everyone recommended different resources and I kept switching between them. After each test, we looked beyond the score and reviewed the type of each mistake. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.
