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!

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
- AP Exams
I was close to my target, but my results changed a lot from one test to the next. Going back to the lesson recordings helped when I forgot a small step. After enough examples of the same question type, the repeated mistakes decreased. I understood that the portfolio needed to show the process, not only the finished piece. I found a better balance between regular school and exam preparation. It was an intense period, but it was worth it.
Alejandra Coronel
- TOEFL iBT
Experiencing the exam format beforehand made test day much less stressful. Over time, Speaking became one of the most organized parts of my TOEFL iBT preparation. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.
Rocio Barros
- IGCSE / GCSE
Our daughter needed regular support with IGCSE Additional Mathematics. We were able to follow the mock results regularly. We thank the tutor and the TestPrep team.
Connor Tully
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. Having the lesson move at my pace made the process feel much easier. I became much more careful with graphs, experiments and data-based questions. The plan changed with my mock and homework results, so the work never felt random. I'm genuinely thankful to my tutor for being patient.
Gavin Franklin
- IB Diploma
I finally understood what was going wrong in IB English A. I started tracking the type of mistake, not just the number of questions I completed. My written answers became shorter, clearer and easier to follow. My preparation became much more regular and easier to track. I found a better balance between regular school and exam preparation. Thanks to TestPrep for helping me stay on track.
Oliver Nolan
- AP Exams
I finally understood what was going wrong in AP Calculus AB. My confidence improved along with the results.
Natalia Varela
- 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.
Vasco Fuentes
- Digital SAT
It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. Seeing the change in our child made us very happy.
Sander Jacobs
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. Over time, IGCSE Psychology became one of the most organized parts of my IGCSE / GCSE preparation. The plan changed with my mock and homework results, so the work never felt random. Source questions became easier once I noticed how small details affected the mark. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.
Valentin Picard
- A-Level
Over time, A-Level Physics became one of the most organized parts of my A-Level preparation. Past-paper questions showed me how different topics could appear together. I started noticing the reason for a mistake much faster.
Manon Reynaud
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. The group never had more than six students, so it was easy to stay involved. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.
Daniela Espinoza
- UCAT
Everyone recommended different resources and I kept switching between them. We didn't spend extra time on things I already knew. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.
Carlotta Fiore
- AP Exams
At the beginning, we knew very little about the AP Exams system as parents. A good connection with the tutor developed quite quickly. Flexible scheduling helped during a demanding school year. The tutor's close attention to weaker areas gave us confidence. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Brianna Freeman
- IMAT
Our son's school schedule was already very busy. Joining lessons willingly was one of the clearest signs for us. Online lessons made it possible to continue without losing time on travel. Mock analysis allowed us to follow progress more clearly. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Kanya Saelim
- IGCSE / GCSE
I was taking IGCSE Sociology at school, but getting used to the exam questions took time. I used the question bank regularly to return to weaker topics. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
Claire McMillan
- IGCSE / GCSE
Having the lesson move at my pace made the process feel much easier. Breaking IGCSE Psychology into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.
Isadora Azevedo
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I stopped doing a huge amount one week and nothing the next. Even in a group lesson, the tutor knew where each of us stood. Knowing the criteria from the start made the whole task less vague. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.
Hyunseok Ko
- GRE General
The feedback I received on Data Analysis was clear and practical. My confidence improved along with the results.
Alfie Hayes
- AP Exams
Over time, AP Statistics became one of the most organized parts of my AP Exams preparation. A quick check after each answer helped me catch small mistakes. My preparation became much more regular and easier to track.
Saki Nishimura
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. Over time, IGCSE Economics became one of the most organized parts of my IGCSE / GCSE preparation. I started tracking the type of mistake, not just the number of questions I completed. Balancing Quant and Verbal in the same week worked better than studying them in blocks. I found a better balance between regular school and exam preparation. Thank you to my tutor and the TestPrep team.
Paula Baez
- UCAT
The UCAT format felt unnecessarily confusing at first. I stopped doing a huge amount one week and nothing the next. I stopped choosing answers by feel and started looking for evidence in the passage. Thanks to TestPrep for helping me stay on track.
Tyler Finley
- PTE Academic
I was taking Listening at school, but getting used to the exam questions took time. Over time, Listening became one of the most organized parts of my PTE Academic preparation. Near the exam, it was clear what to keep doing and what to stop. I learned not to lose the rest of a listening task because I missed one word. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.
Oliver Atkins
- PTE Academic
What annoyed me most was losing easy points because I rushed. My tutor usually asked me to explain my thinking before stepping in. The group never had more than six students, so it was easy to stay involved. I started tracing code line by line instead of only reading it quickly. There was no overnight miracle, but the progress was easy to see. Thank you to my tutor and the TestPrep team.
