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 IB Diploma format felt unnecessarily confusing at first. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Before coding, I began thinking about which structure actually fit the problem. The preparation felt calmer than I expected.
Shota Shimizu
- SSAT
I learned not to spend the same amount of time on every line of a long text. It was an intense period, but it was worth it.
Marco Gatti
- TOEFL iBT
I came back to Speaking after a long break and wasn't sure where to begin. Even in a group lesson, the tutor knew where each of us stood. I developed a clearer way to return to the text during reading questions. My tutor made it easy to ask questions from the first lesson. Questions from other students often helped me as well. Thank you to the tutor who stayed supportive until the end.
Efe Tekin
- LNAT
Flexible scheduling helped during a demanding school year. We were happy with both the teaching and the communication.
Phoebe Lambert
- AP Exams
I was taking AP Macroeconomics at school, but getting used to the exam questions took time. Questions from other students often helped me as well. I became much more comfortable asking questions in class. I'm glad I worked with my tutor through this process.
Jelena Kral
- A-Level
I chose A-Level History this year and wanted to build a solid base from the beginning. We didn't spend extra time on things I already knew. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.
Mason Whitman
- IGCSE / GCSE
I learned to separate the information needed for a decision from the extra detail. I was really happy with the lessons.
Mason Warren
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. Over time, IGCSE Computer Science became one of the most organized parts of my IGCSE / GCSE preparation. I never felt awkward asking the same thing again. Predicting the output helped me catch small logic errors. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.
Tereza Prochazka
- TOEFL iBT
Breaking Speaking into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.
Alessia Bellini
- IB Diploma
We wanted our child to keep up with the school pace in IB Economics. Online lessons made it possible to continue without losing time on travel. The tutor's close attention to weaker areas gave us confidence. We were able to follow the mock results regularly. Flexible scheduling helped during a demanding school year. We would recommend the program to students and families in a similar situation.
Miles Lockwood
- A-Level
I chose A-Level English Literature this year and wanted to build a solid base from the beginning. After a while, the questions started to feel much more familiar.
Arnav Suri
- AP Exams
Everyone recommended different resources and I kept switching between them. Questions from other students often helped me as well. I became much more comfortable asking questions in class. Thanks to everyone who supported me.
Elin Bergman
- IGCSE / GCSE
I finally understood what was going wrong in IGCSE Economics. I wasn't trying to learn new topics at the very last minute.
Ara Sung
- Digital SAT
I was doing questions for SAT Math on my own but never had a steady routine. The preparation felt calmer than I expected.
Ashleigh Yates
- IB Diploma
What annoyed me most was losing easy points because I rushed. Working across different difficulty levels made new questions feel less surprising. The feedback helped me improve my own work without writing it for me. One bad mock no longer made me want to drop the whole plan. Choosing questions by topic made my practice time much more useful. Thanks to TestPrep for helping me stay on track.
Lijuan Zeng
- TOEFL iBT
In Reading, timing was costing me more points than the content itself. Thank you to my tutor and the TestPrep team.
Alejandra Mena
- IB Diploma
Over time, IB Global Politics became one of the most organized parts of my IB Diploma preparation. My preparation became much more regular and easier to track.
Carmen Mota
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. The lessons where I found the bug myself were the ones I remembered best. 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.
Marek Svoboda
- GMAT Focus
I had collected too many resources without knowing when to use any of them. Having the lesson move at my pace made the process feel much easier. Seeing several versions of the same topic made unfamiliar questions less stressful. One bad mock no longer made me want to drop the whole plan. My tutor could see my reasoning and usually found the source of an error quickly. It was an intense period, but it was worth it.
Giulia Coppola
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. A clear plan for the final weeks made priorities much easier to see. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
Matilda Gilmour
- AP Exams
My written answers became shorter, clearer and easier to follow. I was really happy with the lessons.
Sneha Bhatt
- YÖS / TR-YÖS
Our son's school schedule was already very busy. Being able to fit lessons around school made the process easier. Flexible scheduling helped during a demanding school year. The plan was adjusted when school exams became busy. We would recommend the program to students and families in a similar situation.
Elise Renard
- 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. Balancing Quant and Verbal in the same week worked better than studying them in blocks. Thank you to my tutor and the TestPrep team.
Caleb Langston
- A-Level
Keeping up with A-Level while school was busy was harder than I expected. I finally understood what was going wrong in A-Level Art and Design. By the end of each lesson, I knew what I was supposed to do during the week. I understood that the portfolio needed to show the process, not only the finished piece. I went into the exam much calmer than I would have before. The preparation felt calmer than I expected.
