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 PTE Academic format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I learned not to lose the rest of a listening task because I missed one word. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. I was really happy with the lessons.
Skye Ingram
- IELTS Academic
After my first attempt, I wanted a calmer and more focused plan for the retake. The preparation felt calmer than I expected.
Romina Zuniga
- A-Level
Separating strategy mistakes from content gaps made progress much quicker. Thank you to my tutor and the TestPrep team.
Haruka Abe
- IGCSE / GCSE
As the exam got closer, I wasn't sure what I should actually review. I started tracking the type of mistake, not just the number of questions I completed. Having the lesson move at my pace made the process feel much easier. Once I understood the reasons behind the facts, the questions felt less random. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.
Antoine Benoit
- Digital SAT
When I started preparing for Digital SAT, I wasn't sure what order to study things in. We didn't spend extra time on things I already knew. Sorting mistakes after each mock changed the way I studied. The plan changed with my mock and homework results, so the work never felt random. Lesson times could fit around school, university or work. Thanks to TestPrep for helping me stay on track.
Claudia Loureiro
- AP Exams
Our daughter needed regular support with AP European History. Preparation looked calmer and more organized closer to the exam. The tutor supported regular study, not only the lesson content. The class size kept our child from disappearing into the background. Flexible scheduling helped during a demanding school year. We were happy with both the teaching and the communication.
Naina Pillai
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. A lot of my mistakes came from rushing through the wording of the question. I stopped doing a huge amount one week and nothing the next. The class felt relaxed enough to ask questions without overthinking it. Thanks to everyone who supported me.
Jisoo Moon
- AP Exams
Full-length mocks helped me get used to the real exam pace. The feedback I received on AP Environmental Science was clear and practical. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.

Katarina Horvat
- A-Level
I became much more careful with graphs, experiments and data-based questions. It was an intense period, but it was worth it.
Chiara Ferri
- IELTS Academic
The IELTS Academic format felt unnecessarily confusing at first. I finally understood what was going wrong in Academic Reading. By the end of each lesson, I knew what I was supposed to do during the week. I developed a clearer way to return to the text during reading questions. I wasn't trying to learn new topics at the very last minute. I was really happy with the lessons.
Camila Saavedra
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. My tutor made it easy to ask questions from the first lesson. We balanced current school topics with past-paper practice. I learned to make a short plan before starting a long response. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.
Lachlan Menzies
- AP Exams
The plan was adjusted when school exams became busy. We were happy with both the teaching and the communication.
Ceren Kartal
- Digital SAT
After my first attempt, I wanted the second round of preparation to feel more organized. The class felt relaxed enough to ask questions without overthinking it. My written answers became shorter, clearer and easier to follow. The plan changed with my mock and homework results, so the work never felt random. Even in a group lesson, the tutor knew where each of us stood. I'm genuinely thankful to my tutor for being patient.

- IGCSE / GCSE
I can now decide much faster when to move on from a question. I was really happy with the lessons.
Juliana Alarcon
- Digital SAT
I was taking Standard English Conventions at school, but getting used to the exam questions took time. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Full-length mocks helped me get used to the real exam pace. Discussing why the other choices were wrong helped more than I expected. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.
Yuxin Feng
- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. Experiencing the exam format beforehand made test day much less stressful. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.

Breaking AP Computer Science Principles into smaller pieces worked much better for me. I stopped doing a huge amount one week and nothing the next. My written code answers became much more organized.

Riccardo Valentini
- PTE Academic
I was taking Computer-Based Practice at school, but getting used to the exam questions took time. By the end of each lesson, I knew what I was supposed to do during the week. Before coding, I began thinking about which structure actually fit the problem. I was really happy with the lessons.
