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 wasn't starting from zero, but the same mistakes kept showing up in my mocks. I started tracking the type of mistake, not just the number of questions I completed. Source questions became easier once I noticed how small details affected the mark. I'm glad I worked with my tutor through this process.

Breaking AP Seminar into smaller pieces worked much better for me. I left the exam feeling that I had done what I could.

After the first attempt, we looked for a calmer plan for the retake. It was good to see confidence returning over time. A good connection with the tutor developed quite quickly. Regular work on similar question types reduced repeated mistakes. Preparation looked calmer and more organized closer to the exam. We were pleased with the support we received.

I finally understood what was going wrong in Information & Ideas. Sorting mistakes after each mock changed the way I studied. I became much more comfortable asking questions in class.
Callum Yates
- LNAT
The feedback I received on Reading Comprehension was clear and practical. I stopped choosing answers by feel and started looking for evidence in the passage. My confidence improved along with the results.
Stefan Markovic
- IMAT
I was close to my target, but my results changed a lot from one test to the next. We could make the workload lighter during busy weeks at school or university. Past-paper questions showed me how different topics could appear together. It was an intense period, but it was worth it.
James Bennett
- IGCSE / GCSE
Our daughter needed regular support with IGCSE English Literature. Full-length tests showed how time was being used across the exam. We were happy with both the teaching and the communication.
Leandro Machado
- AP Exams
The AP Exams format felt unnecessarily confusing at first. Even in a group lesson, the tutor knew where each of us stood. Balancing Quant and Verbal in the same week worked better than studying them in blocks. I started tracking the type of mistake, not just the number of questions I completed. The group never had more than six students, so it was easy to stay involved. I'm genuinely thankful to my tutor for being patient.

We wanted our child to keep up with the school pace in Biology. Joining lessons willingly was one of the clearest signs for us.
Corentin Benoit
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. Over time, Sentence Equivalence became one of the most organized parts of my GRE General preparation. One bad mock no longer made me want to drop the whole plan. I learned not to spend the same amount of time on every line of a long text. My preparation became much more regular and easier to track. Thanks to everyone who supported me.

After my first attempt, I wanted a calmer and more focused plan for the retake. It was an intense period, but it was worth it.
Marnie Huxley
- IMAT
Working across different difficulty levels made new questions feel less surprising. The feedback I received on Biology was clear and practical. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.
Misaki Sakamoto
- AP Exams
As the exam got closer, I wasn't sure what I should actually review. My tutor could see my reasoning and usually found the source of an error quickly. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Sude Ersoy
- AP Exams
Our son's school schedule was already very busy. Full-length tests showed how time was being used across the exam. Online lessons made it possible to continue without losing time on travel. Preparation looked calmer and more organized closer to the exam. Seeing the change in our child made us very happy.
Brooke Livingston
- IGCSE / GCSE
Over time, IGCSE English Literature became one of the most organized parts of my IGCSE / GCSE preparation. We could make the workload lighter during busy weeks at school or university. I learned not to spend the same amount of time on every line of a long text. After a while, the questions started to feel much more familiar. My mock results gradually became more consistent. A big thank you to my tutor for all the support :)
Maxime Lacroix
- SSAT
As the exam got closer, I wasn't sure what I should actually review. Lesson times could fit around school, university or work. A quick check after each answer helped me catch small mistakes. I started tracking the type of mistake, not just the number of questions I completed. My tutor could see my reasoning and usually found the source of an error quickly. Thank you to my tutor and the TestPrep team.
Hamish McIntyre
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. Thank you to my tutor and the TestPrep team.
Koen Dietrich
- ACT
I was doing questions for ACT Reading on my own but never had a steady routine. It was an intense period, but it was worth it.
Phoebe Sutherland
- IGCSE / GCSE
I was taking IGCSE Chemistry at school, but getting used to the exam questions took time. Over time, IGCSE Chemistry became one of the most organized parts of my IGCSE / GCSE preparation. 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 left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Reagan Keegan
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. Near the exam, it was clear what to keep doing and what to stop. I learned to make a short plan before starting a long response. The preparation felt calmer than I expected.
Lauren Pritchard
- A-Level
I was doing questions for A-Level English Literature on my own but never had a steady routine. My mock results gradually became more consistent.
Erin Donovan

Everyone recommended different resources and I kept switching between them. Thanks to TestPrep for helping me stay on track.
Mei Watanabe
- AP Exams
The AP Exams format felt unnecessarily confusing at first. My tutor made it easy to ask questions from the first lesson. My tutor could see my reasoning and usually found the source of an error quickly. My written answers became shorter, clearer and easier to follow. Knowing what to study reduced a lot of the stress. Thank you to the tutor who stayed supportive until the end.

I became much more careful with graphs, experiments and data-based questions. I'm glad I worked with my tutor through this process.
