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!

Over time, IGCSE English as a Second Language 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. I learned not to spend the same amount of time on every line of a long text. I became much more comfortable asking questions in class. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

- PTE Academic
We noticed that the resources kept changing during independent study. The lessons started being followed without constant reminders from us. Being able to fit lessons around school made the process easier. The tutor supported regular study, not only the lesson content. Mistakes became something to work on rather than something to feel bad about. We thank the tutor and the TestPrep team.
Quang Cao
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. Knowing what to study reduced a lot of the stress.
Klara Wagner
- TOEFL iBT
I finally understood what was going wrong in Reading. I developed a clearer way to return to the text during reading questions. There was no overnight miracle, but the progress was easy to see.
Carolina Vieira
- IB Diploma
Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Tiago Simoes
- GRE General
I came back to Verbal Reasoning after a long break and wasn't sure where to begin. I stopped doing a huge amount one week and nothing the next. Full-length mocks helped me get used to the real exam pace. Discussing why the other choices were wrong helped more than I expected. I left the exam feeling that I had done what I could. I'm genuinely thankful to my tutor for being patient.
Marko Holm
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. The class felt relaxed enough to ask questions without overthinking it. Connecting examples back to the main point made my writing more consistent. One bad mock no longer made me want to drop the whole plan. Questions from other students often helped me as well. I'm glad I worked with my tutor through this process.
Beatriz Cunha
- PTE Academic
I came back to Computer-Based Practice after a long break and wasn't sure where to begin. Going back to the lesson recordings helped when I forgot a small step. My written code answers became much more organized. Thanks to TestPrep for helping me stay on track.
Linnea Bakke
- GMAT Focus
After my first attempt, I wanted a calmer and more focused plan for the retake. I wasn't trying to learn new topics at the very last minute.
Lorenzo DeLuca
- AP Exams
Our child wasn't sure how to organize the preparation for AP Exams. We were able to follow the mock results regularly. Thank you sincerely to everyone involved.
Romain Masson
- Digital SAT
I was taking Information & Ideas at school, but getting used to the exam questions took time. Thank you to my tutor and the TestPrep team.
Ignacio Santillan
- AP Exams
Everyone recommended different resources and I kept switching between them. Lesson times could fit around school, university or work. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)
Rodrigo Nascimento
- TOEFL iBT
We wanted our child to keep up with the school pace in Speaking. Individual lesson time was used around our child's actual needs. We were happy with both the teaching and the communication.
Leandro Villalba
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. 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. The feedback helped me improve my own work without writing it for me. There was no overnight miracle, but the progress was easy to see. I was really happy with the lessons.
Camden Sutton
- AP Exams
I was taking AP English Language at school, but getting used to the exam questions took time. It was an intense period, but it was worth it.
Mai Vu
- SSAT
At the beginning, we knew very little about the SSAT system as parents. The lessons started being followed without constant reminders from us. Regular mocks built familiarity with the real exam pace. Flexible scheduling helped during a demanding school year. A good connection with the tutor developed quite quickly. Seeing the change in our child made us very happy.
Caleb Patterson
- Digital SAT
Over time, Reading & Writing became one of the most organized parts of my Digital SAT preparation. I stopped choosing answers by feel and started looking for evidence in the passage. Knowing what to study reduced a lot of the stress.
Gustavo Santana
- IGCSE / GCSE
Over time, IGCSE Combined Science became one of the most organized parts of my IGCSE / GCSE preparation. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. My confidence improved along with the results.
Jisung Moon
- LSAT
I learned not to spend the same amount of time on every line of a long text. I'm genuinely thankful to my tutor for being patient.
Naoki Ikeda
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Timed work showed exactly which section was slowing me down. Thanks to TestPrep for helping me stay on track.
Stefan Stanic
- GRE General
Lesson times could fit around school, university or work. Over time, Quantitative Reasoning became one of the most organized parts of my GRE General preparation. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.
Tao Zhu
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. My mock results gradually became more consistent.
