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 Information & Ideas into smaller pieces worked much better for me. I wasn't trying to learn new topics at the very last minute.
Minji Oh
- GRE General
I came back to Text Completion after a long break and wasn't sure where to begin. Over time, Text Completion became one of the most organized parts of my GRE General preparation. Going back to the lesson recordings helped when I forgot a small step. I stopped choosing answers by feel and started looking for evidence in the passage. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.

I was taking AP Calculus AB at school, but getting used to the exam questions took time. I could work on exam technique without falling behind in class. We focused more on understanding what the problem asked than memorizing formulas. The plan changed with my mock and homework results, so the work never felt random. I'm glad I worked with my tutor through this process.
Mengyao Xia
- PTE Academic
I was taking Reading at school, but getting used to the exam questions took time. The plan changed with my mock and homework results, so the work never felt random. Questions from other students often helped me as well. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.
Trevor Preston
- LSAT
Balancing LSAT preparation with university and work was harder than I expected. Having the lesson move at my pace made the process feel much easier. My written answers became shorter, clearer and easier to follow. 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.

- IGCSE / GCSE
What annoyed me most was losing easy points because I rushed. I was really happy with the lessons.
Klara Devries
- Digital SAT
After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.
Ruby Tully
- IB Diploma
We didn't spend extra time on things I already knew. Breaking IB English B into smaller pieces worked much better for me. I left the exam feeling that I had done what I could. I was really happy with the lessons.
Maddison Connors
- A-Level
Anxiety became more visible as the exam got closer. The question bank made independent work between lessons much clearer. We quickly felt that the tutor was a good match.
Marnie Tarrant
- PTE Academic
I chose Reading this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.
Cooper Elliott
- AP Exams
The feedback helped me improve my own work without writing it for me. I was really happy with the lessons.
Antoine Faure
- IGCSE / GCSE
Our child had a clear goal but no steady study routine. A good connection with the tutor developed quite quickly. Being able to fit lessons around school made the process easier. Joining lessons willingly was one of the clearest signs for us. We were happy with both the teaching and the communication.
Marnie Goodall
- IGCSE / GCSE
Over time, IGCSE Economics became one of the most organized parts of my IGCSE / GCSE preparation. My tutor usually asked me to explain my thinking before stepping in. With data-heavy questions, I began reading the task before getting lost in the table. I found a better balance between regular school and exam preparation. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.
Davide Santoro
- IB Diploma
The feedback I received on IB Chemistry was clear and practical. I found a better balance between regular school and exam preparation.
Burak Bilgin
- IB Diploma
We wanted our child to keep up with the school pace in IB ESS. Thank you sincerely to everyone involved.
Trent Templeton
- AP Exams
Over time, AP Research became one of the most organized parts of my AP Exams preparation. Near the exam, it was clear what to keep doing and what to stop. I realized that choosing a topic, researching and revising each needed its own deadline. 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. I'm genuinely thankful to my tutor for being patient.
Nicolas Chacon
- IELTS Academic
In Academic Reading, timing was costing me more points than the content itself. We didn't spend extra time on things I already knew. I learned not to lose the rest of a listening task because I missed one word. Near the exam, it was clear what to keep doing and what to stop. Having the lesson move at my pace made the process feel much easier. Thanks to TestPrep for helping me stay on track.
Dylan Goodwin
- IB Diploma
Over time, Extended Essay (EE) became one of the most organized parts of my IB Diploma preparation. Breaking the draft into smaller parts made it feel much more doable. I found a better balance between regular school and exam preparation.
Koen Brandt
- Digital SAT
What annoyed me most was losing easy points because I rushed. I finally understood what was going wrong in Problem Solving & Data Analysis. Near the exam, it was clear what to keep doing and what to stop. Learning when to leave a hard question made a real difference to my timing. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.
Florian Caron
- SSAT
Everyone recommended different resources and I kept switching between them. Even in a group lesson, the tutor knew where each of us stood. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Spencer Barlow
- YÖS / TR-YÖS
The feedback I received on Mathematics was clear and practical. After a while, the questions started to feel much more familiar.
Paula Mendoza

After the first attempt, we looked for a calmer plan for the retake. Being able to fit lessons around school made the process easier. We were pleased with the support we received.
Ngoc Nguyen
- AP Exams
We noticed that the resources kept changing during independent study. The tutor supported regular study, not only the lesson content. Topic-based question practice made study time more focused. It was good to see confidence returning over time. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.
Logan Dean
- IGCSE / GCSE
Breaking IGCSE Environmental Management into smaller pieces worked much better for me. By the end of each lesson, I knew what I was supposed to do during the week. Separating calculation errors from content gaps made revision more useful. I found a better balance between regular school and exam preparation. My mock results gradually became more consistent. The preparation felt calmer than I expected.
