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!

Knowing the criteria from the start made the whole task less vague. I'm genuinely thankful to my tutor for being patient.

The IB Diploma format felt unnecessarily confusing at first. The feedback I received on IB Geography was clear and practical. Going back to the lesson recordings helped when I forgot a small step. Using the mark scheme to review my own answer was surprisingly helpful. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.

I chose IB Chemistry 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. Once I understood the reasons behind the facts, the questions felt less random. A big thank you to my tutor for all the support :)
Lewis Chandler
- 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
- 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
- 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
- IB Diploma
The mocks showed where my time was actually being lost. I finally understood what was going wrong in IB Visual Arts. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.

The plan was adjusted when school exams became busy. Communication with the team was straightforward and our questions were answered. Thank you sincerely to everyone involved.
Austin Atwood
- IB Diploma
I was taking Extended Essay (EE) at school, but getting used to the exam questions took time. I found a better balance between regular school and exam preparation.
Rizky Nugroho
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. My tutor made it easy to ask questions from the first lesson. Keeping school units and exam preparation in the same plan worked really well. The feedback helped me improve my own work without writing it for me. My mock results gradually became more consistent. I'm glad I worked with my tutor through this process.
Tolga Ersoy
- IB Diploma
Our child wasn't sure how to organize the preparation for IB Diploma. Thank you sincerely to everyone involved.
Lucy Webster

The feedback I received on IB Computer Science was clear and practical. Predicting the output helped me catch small logic errors. My preparation became much more regular and easier to track.

Samuele Fiore
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. I worked on keeping a steady pace instead of rushing the easy questions. I'm genuinely thankful to my tutor for being patient.
Felix Peeters
- IB Diploma
I chose IB Physics this year and wanted to build a solid base from the beginning. We could make the workload lighter during busy weeks at school or university. Past-paper questions showed me how different topics could appear together. Thanks to everyone who supported me.
Matilda Templeton
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. I finally understood what was going wrong in Extended Essay (EE). The plan changed with my mock and homework results, so the work never felt random. Knowing the criteria from the start made the whole task less vague. I found a better balance between regular school and exam preparation. It was an intense period, but it was worth it.
Mitchell Hawke
- IB Diploma
Over time, IB Business Management became one of the most organized parts of my IB Diploma preparation. My preparation became much more regular and easier to track.
Andrea Portillo
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. The plan changed with my mock and homework results, so the work never felt random. Breaking the draft into smaller parts made it feel much more doable. Thank you to the tutor who stayed supportive until the end.
Camden Carver
- IB Diploma
Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Tiago Simoes
- 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
- IB Diploma
Keeping up with IB Diploma while school was busy was harder than I expected. I used the question bank regularly to return to weaker topics. Knowing the criteria from the start made the whole task less vague. I stopped doing a huge amount one week and nothing the next. Choosing questions by topic made my practice time much more useful. The preparation felt calmer than I expected.
Morgan Hawkins
- IB Diploma
The tutor supported regular study, not only the lesson content. The overall experience was positive from beginning to end.
Rita Leitao
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Even in a group lesson, the tutor knew where each of us stood. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. The plan changed with my mock and homework results, so the work never felt random. Questions from other students often helped me as well. A big thank you to my tutor for all the support :)
