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 Verbal was clear and practical. I started noticing the reason for a mistake much faster.
Imogen Ridley
- A-Level
The A-Level format felt unnecessarily confusing at first. The group never had more than six students, so it was easy to stay involved. I learned to separate the information needed for a decision from the extra detail. One bad mock no longer made me want to drop the whole plan. The class felt relaxed enough to ask questions without overthinking it. A big thank you to my tutor for all the support :)
Bora Cha
- A-Level
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. One bad mock no longer made me want to drop the whole plan. I could work on exam technique without falling behind in class. I started seeing shorter solutions that were easier to check under time pressure. My mock results gradually became more consistent. I was really happy with the lessons.

Breaking AP Computer Science Principles into smaller pieces worked much better for me. My confidence improved along with the results.
Bruna Nunes
- IB Diploma
After enough examples of the same question type, the repeated mistakes decreased. The feedback I received on Extended Essay (EE) was clear and practical. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

- AP Exams
I finally understood what was going wrong in AP Calculus BC. I stopped doing a huge amount one week and nothing the next. A quick check after each answer helped me catch small mistakes. I became much more comfortable asking questions in class. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.
Woojin Jin
- LNAT
We wanted our child to keep up with the school pace in Argument Analysis. A good connection with the tutor developed quite quickly. Joining lessons willingly was one of the clearest signs for us. The tutor's close attention to weaker areas gave us confidence. Flexible scheduling helped during a demanding school year. Thank you sincerely to everyone involved.

I was taking Verbal Reasoning at school, but getting used to the exam questions took time. A big thank you to my tutor for all the support :)
Bea Valdez
- GMAT Focus
In Data Sufficiency, timing was costing me more points than the content itself. Even in a group lesson, the tutor knew where each of us stood. I learned to separate the information needed for a decision from the extra detail. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. A big thank you to my tutor for all the support :)

I came back to Reading after a long break and wasn't sure where to begin. The preparation felt calmer than I expected.
Eduardo Nascimento
- A-Level
I chose A-Level Business this year and wanted to build a solid base from the beginning. Breaking A-Level Business into smaller pieces worked much better for me. Near the exam, it was clear what to keep doing and what to stop. Balancing Quant and Verbal in the same week worked better than studying them in blocks. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

Breaking IGCSE Economics into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see.
Bora Min
- GMAT Focus
Learning when to leave a hard question made a real difference to my timing. I'm glad I worked with my tutor through this process.
Phoebe Callaghan
- A-Level
Keeping up with A-Level while school was busy was harder than I expected. I'm glad I worked with my tutor through this process.
Ethan Raines
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. A clear plan for the final weeks made priorities much easier to see. I started noticing the reason for a mistake much faster. I'm glad I worked with my tutor through this process.
Brianna Chandler
- GMAT Focus
I had been studying alone, but my results stopped improving after a point. Breaking Reading Comprehension into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. A lot of my mistakes came from rushing through the wording of the question. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.
Amelie Chartier
- A-Level
I was close to my target, but my results changed a lot from one test to the next. Over time, A-Level Psychology became one of the most organized parts of my A-Level preparation. Near the exam, it was clear what to keep doing and what to stop. I stopped listing facts in essays and started building an actual argument. Knowing what to study reduced a lot of the stress. I'm genuinely thankful to my tutor for being patient.
Maya Carver
- AP Exams
The feedback I received on AP English Literature was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Discussing why the other choices were wrong helped more than I expected. My mock results gradually became more consistent. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)
Linnea Wozniak
- AP Exams
As the exam got closer, I wasn't sure what I should actually review. After each test, we looked beyond the score and reviewed the type of each mistake. I started tracing code line by line instead of only reading it quickly. I never felt awkward asking the same thing again. Experiencing the exam format beforehand made test day much less stressful. I'm glad I worked with my tutor through this process.
Fabien Couturier
- IELTS Academic
A good connection with the tutor developed quite quickly. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.
Marcos Campos
- YÖS / TR-YÖS
I was doing questions for IQ & Logic on my own but never had a steady routine. I went into the exam much calmer than I would have before.
Ignacio Paredes
- IGCSE / GCSE
Breaking IGCSE Statistics into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. We focused more on understanding what the problem asked than memorizing formulas. I started noticing the reason for a mistake much faster. My confidence improved along with the results. Thank you to my tutor and the TestPrep team.

I was doing questions for Advanced Math on my own but never had a steady routine. I started tracking the type of mistake, not just the number of questions I completed. I started seeing shorter solutions that were easier to check under time pressure. Thanks to everyone who supported me.
