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!

Breaking A-Level Economics into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. I learned to separate the information needed for a decision from the extra detail. I found a better balance between regular school and exam preparation. There was no overnight miracle, but the progress was easy to see. I was really happy with the lessons.

Even in a group lesson, the tutor knew where each of us stood. Over time, A-Level Biology became one of the most organized parts of my A-Level preparation. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.

A good connection with the tutor developed quite quickly. The overall experience was positive from beginning to end.
Julian Werner

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Having the lesson move at my pace made the process feel much easier. I learned to separate the information needed for a decision from the extra detail. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.

Past-paper questions showed me how different topics could appear together. I'm genuinely thankful to my tutor for being patient.
Ming Peng
- A-Level
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Near the exam, it was clear what to keep doing and what to stop. The mocks showed where my time was actually being lost. I stopped listing facts in essays and started building an actual argument. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.
Chiara Costa

Questions from other students often helped me as well. Over time, A-Level Accounting became one of the most organized parts of my A-Level preparation. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

Balancing Quant and Verbal in the same week worked better than studying them in blocks. I was really happy with the lessons.
Eliza Redfern
- 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.

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.

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

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.

I chose A-Level History this year and wanted to build a solid base from the beginning. I wasn't trying to learn new topics at the very last minute.
Chihiro Saito

I became much more careful with graphs, experiments and data-based questions. Thank you to my tutor and the TestPrep team.
Theo Gerard
- A-Level
I was taking A-Level Mathematics at school, but getting used to the exam questions took time. My tutor usually asked me to explain my thinking before stepping in. Working across different difficulty levels made new questions feel less surprising. Learning when to leave a hard question made a real difference to my timing. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.
Mitchell Franklin

Anxiety became more visible as the exam got closer. We were happy with both the teaching and the communication.
Mei Fujita
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. I started tracking the type of mistake, not just the number of questions I completed. A quick check after each answer helped me catch small mistakes. I was really happy with the lessons.
Leandro Santos
- A-Level
Everyone recommended different resources and I kept switching between them. During the intensive review, we returned to real gaps instead of restarting everything. I went into the exam much calmer than I would have before. I'm glad I worked with my tutor through this process.
Gabriel Campos
- A-Level
We noticed that the resources kept changing during independent study. With no more than six students, the tutor had time for everyone. We would recommend the program to students and families in a similar situation.
