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!

The IB Diploma format felt unnecessarily confusing at first. The feedback I received on IB TITC was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Practicing in the real exam format made test day feel much less unfamiliar. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

The plan was adjusted when school exams became busy. It was good to see confidence returning over time. We thank the tutor and the TestPrep team.

I was doing questions for Section B Essay on my own but never had a steady routine. A big thank you to my tutor for all the support :)

I finally understood what was going wrong in A-Level Biology. Knowing what to study reduced a lot of the stress.
Rafael Machado
- IB Diploma
Over time, IB Geography became one of the most organized parts of my IB Diploma preparation. Going back to the lesson recordings helped when I forgot a small step. I stopped listing facts in essays and started building an actual argument. There was no overnight miracle, but the progress was easy to see. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.
Romina Carvajal
- IGCSE / GCSE
Discussing why the other choices were wrong helped more than I expected. A big thank you to my tutor for all the support :)
Beatrice Ferrara
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. My tutor made it easy to ask questions from the first lesson. Source questions became easier once I noticed how small details affected the mark. The preparation felt calmer than I expected.
Harrison Paterson
- IB Diploma
I realized that choosing a topic, researching and revising each needed its own deadline. It was an intense period, but it was worth it.
Renato Pinheiro
- SSAT
The feedback I received on Middle Level was clear and practical. I can now decide much faster when to move on from a question. I started noticing the reason for a mistake much faster.
Tianyu Su
- IB Diploma
Breaking IB ESS into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.
Georgia Bennett
- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. We could make the workload lighter during busy weeks at school or university. Lesson times could fit around school, university or work. My written answers became shorter, clearer and easier to follow. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
Phoebe Murray
- IMAT
I finally understood what was going wrong in Chemistry. There was no overnight miracle, but the progress was easy to see.
Louis Picard
- IMAT
After my first attempt, I wanted the second round of preparation to feel more organized. A big thank you to my tutor for all the support :)
Sienna Rawson
- A-Level
Joining lessons willingly was one of the clearest signs for us. We were happy with both the teaching and the communication.
Gustavo Rezende
- Digital SAT
Anxiety became more visible as the exam got closer. Being able to fit lessons around school made the process easier. We quickly felt that the tutor was a good match.
Luca Greco
- GMAT Focus
I came back to Reading Comprehension after a long break and wasn't sure where to begin. I started tracking the type of mistake, not just the number of questions I completed. Discussing why the other choices were wrong helped more than I expected. Thank you to the tutor who stayed supportive until the end.
Camila Monteiro
- ACT
Flexible scheduling helped during a demanding school year. A good connection with the tutor developed quite quickly. The overall experience was positive from beginning to end.
Gaia Donati
- GRE General
After my first attempt, I wanted a calmer and more focused plan for the retake. I became much more comfortable asking questions in class.
Nari Heo
- IB Diploma
I was doing questions for IB Economics on my own but never had a steady routine. Over time, IB Economics became one of the most organized parts of my IB Diploma preparation. My tutor made it easy to ask questions from the first lesson. My case responses became more organized and direct. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.
Daniela Ponce
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. After a while, the questions started to feel much more familiar.
Mitchell Newell
- SSAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Having the lesson move at my pace made the process feel much easier. I learned not to spend the same amount of time on every line of a long text. Near the exam, it was clear what to keep doing and what to stop. Lesson times could fit around school, university or work. It was an intense period, but it was worth it.
Xiaoyu Xie
- IGCSE / GCSE
Our son's school schedule was already very busy. Online lessons made it possible to continue without losing time on travel. We were able to follow the mock results regularly. Regular mocks built familiarity with the real exam pace. The lessons started being followed without constant reminders from us. We quickly felt that the tutor was a good match.
Jade Templeton
- AP Exams
I was taking AP Calculus AB at school, but getting used to the exam questions took time. A big thank you to my tutor for all the support :)
Gabriela Reinoso
- ACT
After my first attempt, I wanted the second round of preparation to feel more organized. The feedback I received on Optional Writing was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I learned not to spend the same amount of time on every line of a long text. I found a better balance between regular school and exam preparation. Thank you to my tutor and the TestPrep team.
