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 learned not to lose the rest of a listening task because I missed one word. I'm genuinely thankful to my tutor for being patient.
Sebastian Zamora
- ACT
As the exam got closer, I wasn't sure what I should actually review. I finally understood what was going wrong in ACT Math. The plan changed with my mock and homework results, so the work never felt random. Learning when to leave a hard question made a real difference to my timing. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.
Coralie Aubert
- AP Exams
Breaking AP Seminar into smaller pieces worked much better for me. Keeping the sources organized saved a lot of time later. I became much more comfortable asking questions in class.
Brodie McKenzie
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.
Camila Braga
- AP Exams
Over time, AP Physics 2 became one of the most organized parts of my AP Exams preparation. I found a better balance between regular school and exam preparation.
Dylan Lawrence
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. Thanks to TestPrep for helping me stay on track.
Krit Thongdee
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. I finally understood what was going wrong in IB World History. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Connecting examples back to the main point made my writing more consistent. Knowing what to study reduced a lot of the stress. The preparation felt calmer than I expected.
Rina Mori
- SSAT
I finally understood what was going wrong in Writing Sample. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation.
Georgia Garland
- SSAT
Over time, Middle Level became one of the most organized parts of my SSAT preparation. My confidence improved along with the results.

- IGCSE / GCSE
I was taking IGCSE Computer Science at school, but getting used to the exam questions took time. Thank you to my tutor and the TestPrep team.

- A-Level
We noticed that the resources kept changing during independent study. Flexible scheduling helped during a demanding school year. We were pleased with the support we received.
Dong Xu
- IB Diploma
Keeping school units and exam preparation in the same plan worked really well. Over time, IB English B became one of the most organized parts of my IB Diploma preparation. I went into the exam much calmer than I would have before. I was really happy with the lessons.
Claire Ellison
- ACT
I chose ACT Math this year and wanted to build a solid base from the beginning. Breaking ACT Math into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. A quick check after each answer helped me catch small mistakes. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.
Rina Kimura
- AP Exams
What annoyed me most was losing easy points because I rushed. I could work on exam technique without falling behind in class. Knowing what to study reduced a lot of the stress. I was really happy with the lessons.
Rohit Chawla
- ACT
My written answers became shorter, clearer and easier to follow. Thank you to the tutor who stayed supportive until the end.
Garrett Driscoll
- IGCSE / GCSE
The feedback I received on IGCSE Additional Mathematics was clear and practical. One bad mock no longer made me want to drop the whole plan. Learning when to leave a hard question made a real difference to my timing. I left the exam feeling that I had done what I could. I wasn't trying to learn new topics at the very last minute. A big thank you to my tutor for all the support :)
Mauricio Cisneros
- LNAT
Keeping up with LNAT while school was busy was harder than I expected. I left the exam feeling that I had done what I could.

- LSAT
Lesson times could fit around school, university or work. I finally understood what was going wrong in Argumentative Writing. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.
Peiyu Sun
- IGCSE / GCSE
I chose IGCSE Geography this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.

Lalita Lertchai
- LSAT
Over time, Reading Comprehension became one of the most organized parts of my LSAT preparation. I stopped doing a huge amount one week and nothing the next. 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. I left the exam feeling that I had done what I could. I was really happy with the lessons.
Antonia Quezada
- UCAT
The UCAT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.
