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!

I was close to my target, but my results changed a lot from one test to the next. The class felt relaxed enough to ask questions without overthinking it. My mock results gradually became more consistent. Thanks to everyone who supported me.
Nikola Kowalski
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Sorting mistakes after each mock changed the way I studied. Thanks to TestPrep for helping me stay on track.
Cheng Xie
- IB Diploma
At the beginning, we knew very little about the IB Diploma system as parents. Full-length tests showed how time was being used across the exam. We thank the tutor and the TestPrep team.
Luisa Hartmann
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. My tutor could see my reasoning and usually found the source of an error quickly. My preparation became much more regular and easier to track. I'm genuinely thankful to my tutor for being patient.
Cody Baird
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. After a while, the questions started to feel much more familiar.
Asli Turan
- IGCSE / GCSE
Our son's school schedule was already very busy. Individual lesson time was used around our child's actual needs. We quickly felt that the tutor was a good match.
Riccardo Grimaldi
- A-Level
Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.
Holly Gibson
- TOEFL iBT
Everyone recommended different resources and I kept switching between them. I finally understood what was going wrong in Integrated Tasks. I never felt awkward asking the same thing again. I learned not to lose the rest of a listening task because I missed one word. I started noticing the reason for a mistake much faster. I was really happy with the lessons.
Bonnie Lockwood
- AP Exams
After my first attempt, I wanted the second round of preparation to feel more organized. My confidence improved along with the results.
Delaney Mercer
- IB Diploma
Everyone recommended different resources and I kept switching between them. I finally understood what was going wrong in IB Geography. One bad mock no longer made me want to drop the whole plan. Connecting examples back to the main point made my writing more consistent. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Keira Atkinson
- AP Exams
The feedback I received on AP Computer Science A was clear and practical. My tutor made it easy to ask questions from the first lesson. Predicting the output helped me catch small logic errors. My mock results gradually became more consistent. I went into the exam much calmer than I would have before. It was an intense period, but it was worth it.
Julian Montoya
- AP Exams
We weren't sure whether online lessons would be effective. Joining lessons willingly was one of the clearest signs for us. The plan was adjusted when school exams became busy. Being able to fit lessons around school made the process easier. The tutor supported regular study, not only the lesson content. We quickly felt that the tutor was a good match.
Jasmine Moroney
- UCAT
I was doing questions for Time Management on my own but never had a steady routine. A big thank you to my tutor for all the support :)
Romina Chacon
- ACT
What annoyed me most was losing easy points because I rushed. Near the exam, it was clear what to keep doing and what to stop. A lot of my mistakes came from rushing through the wording of the question. A big thank you to my tutor for all the support :)
Jasmine Langford
- IGCSE / GCSE
We weren't sure whether online lessons would be effective. Online lessons made it possible to continue without losing time on travel. Individual lesson time was used around our child's actual needs. We thank the tutor and the TestPrep team.
Yuxin Liu
- ACT
The feedback I received on ACT Science was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Past-paper questions showed me how different topics could appear together. Knowing what to study reduced a lot of the stress. I found a better balance between regular school and exam preparation. Thanks to everyone who supported me.
Nico Kramer
- AP Exams
As the exam got closer, I wasn't sure what I should actually review. I stopped doing a huge amount one week and nothing the next. I used the question bank regularly to return to weaker topics. My written code answers became much more organized. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.
Buse Ekinci
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. Lesson times could fit around school, university or work. Practicing in the real exam format made test day feel much less unfamiliar. Going back to the lesson recordings helped when I forgot a small step. Thank you to my tutor and the TestPrep team.
Giulia Fiore
- PTE Academic
I came back to Write from Dictation after a long break and wasn't sure where to begin. The mocks showed where my time was actually being lost. My mock results gradually became more consistent. Thanks to TestPrep for helping me stay on track.
Blake Atkinson
- GRE General
Over time, Text Completion became one of the most organized parts of my GRE General preparation. By the end of each lesson, I knew what I was supposed to do during the week. I stopped choosing answers by feel and started looking for evidence in the passage. I went into the exam much calmer than I would have before. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.
Levi Hume
- PTE Academic
Our daughter needed regular support with Repeat Sentence. Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. Being able to fit lessons around school made the process easier. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.
