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!

Breaking IB Economics into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.

- IB Diploma
We wanted our child to keep up with the school pace in IB Global Politics. Returning to actual gaps instead of restarting everything saved time. The overall experience was positive from beginning to end.

When I started preparing for IB Diploma, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. Timed work showed exactly which section was slowing me down. The preparation felt calmer than I expected.

Anxiety became more visible as the exam got closer. Full-length tests showed how time was being used across the exam. Thank you sincerely to everyone involved.
Declan Menzies
- IB Diploma
I chose IB English A this year and wanted to build a solid base from the beginning. By the end of each lesson, I knew what I was supposed to do during the week. Discussing why the other choices were wrong helped more than I expected. Thank you to the tutor who stayed supportive until the end.
Cody Yates
- IB Diploma
At the beginning, we knew very little about the IB Diploma system as parents. It was good to see confidence returning over time. Full-length tests showed how time was being used across the exam. The plan was adjusted when school exams became busy. Seeing the change in our child made us very happy.
Fraser Hargreaves
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
Chelsea Norris
- IB Diploma
During the intensive review, we returned to real gaps instead of restarting everything. I finally understood what was going wrong in IB Visual Arts. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)
Alba Loureiro
- IB Diploma
Our child had a clear goal but no steady study routine. Individual lesson time was used around our child's actual needs. 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.
Chelsea McKenzie
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I realized that choosing a topic, researching and revising each needed its own deadline. I was really happy with the lessons.
Garrett Harmon
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. I wasn't trying to learn new topics at the very last minute.
Marko Ilic
- IB Diploma
Our son's school schedule was already very busy. Preparation looked calmer and more organized closer to the exam. We would recommend the program to students and families in a similar situation.
Natalia Santana
- IB Diploma
Everyone recommended different resources and I kept switching between them. I'm glad I worked with my tutor through this process.
Leif Nygard
- IB Diploma
I finally understood what was going wrong in IB English B. I stopped choosing answers by feel and started looking for evidence in the passage. There was no overnight miracle, but the progress was easy to see.
Jasmine Hume
- IB Diploma
We wanted our child to keep up with the school pace in IB Computer Science. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.
Joonho Seo
- IB Diploma
I was doing questions for IB Computer Science on my own but never had a steady routine. I stopped doing a huge amount one week and nothing the next. School assignments and internal exam dates were included in the schedule. My written code answers became much more organized. Knowing what to study reduced a lot of the stress. Thank you to my tutor and the TestPrep team.
Georgia Haines
- IB Diploma
Flexible scheduling helped during a demanding school year. Mistakes became something to work on rather than something to feel bad about. We quickly felt that the tutor was a good match.
Luisa Willems
- IB Diploma
I was taking IB Biology at school, but getting used to the exam questions took time. One bad mock no longer made me want to drop the whole plan. I became much more careful with graphs, experiments and data-based questions. I'm genuinely thankful to my tutor for being patient.
Matilde Pires
- IB Diploma
I worked on keeping a steady pace instead of rushing the easy questions. The preparation felt calmer than I expected.
Cassidy Raines
- IB Diploma
After the first attempt, we looked for a calmer plan for the retake. The tutor's close attention to weaker areas gave us confidence. Joining lessons willingly was one of the clearest signs for us. Communication with the team was straightforward and our questions were answered. Seeing the change in our child made us very happy.
Pilar Zamora
- IB Diploma
Our child wasn't sure how to organize the preparation for IB Diploma. The tutor's close attention to weaker areas gave us confidence. Online lessons made it possible to continue without losing time on travel. It was good to see confidence returning over time. We were happy with both the teaching and the communication.
Seungwoo Kim
- IB Diploma
I was doing questions for IB Visual Arts on my own but never had a steady routine. Near the exam, it was clear what to keep doing and what to stop. Even in a group lesson, the tutor knew where each of us stood. Reviewing my work against the criteria changed the way I edited it. After a while, the questions started to feel much more familiar. Thanks to everyone who supported me.
Seulgi Kwak
- IB Diploma
Breaking IB Visual Arts into smaller pieces worked much better for me. The feedback was clear enough that I always knew what to revise next. I found a better balance between regular school and exam preparation.
Jack Pemberton

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I left the exam feeling that I had done what I could.
