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!

What annoyed me most was losing easy points because I rushed. Going back to the lesson recordings helped when I forgot a small step. Discussing why the other choices were wrong helped more than I expected. A big thank you to my tutor for all the support :)

Breaking AP US Government into smaller pieces worked much better for me. Using the mark scheme to review my own answer was surprisingly helpful. My confidence improved along with the results.

- YÖS / TR-YÖS
I was doing questions for Mathematics on my own but never had a steady routine. Even in a group lesson, the tutor knew where each of us stood. Learning when to leave a hard question made a real difference to my timing. My tutor usually asked me to explain my thinking before stepping in. Thank you to my tutor and the TestPrep team.

- Digital SAT
I was doing questions for Problem Solving & Data Analysis on my own but never had a steady routine. My tutor usually asked me to explain my thinking before stepping in. Seeing several versions of the same topic made unfamiliar questions less stressful. Thanks to everyone who supported me.

- IB Diploma
I was doing questions for IB English B on my own but never had a steady routine. My tutor usually asked me to explain my thinking before stepping in. I learned not to spend the same amount of time on every line of a long text. Thanks to everyone who supported me.
Remi Perrin
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. We didn't spend extra time on things I already knew. Seeing several versions of the same topic made unfamiliar questions less stressful. Going back to the lesson recordings helped when I forgot a small step. Thanks to everyone who supported me.
Rocio Prieto
- SSAT
As the exam got closer, I wasn't sure what I should actually review. After each test, we looked beyond the score and reviewed the type of each mistake. Learning when to leave a hard question made a real difference to my timing. Near the exam, it was clear what to keep doing and what to stop. Experiencing the exam format beforehand made test day much less stressful. I was really happy with the lessons.

We wanted our child to keep up with the school pace in Algebra. Communication with the team was straightforward and our questions were answered. We quickly felt that the tutor was a good match.

The feedback I received on Verbal Reasoning was clear and practical. A lot of my mistakes came from rushing through the wording of the question. I found a better balance between regular school and exam preparation.
Kohei Watanabe
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor made it easy to ask questions from the first lesson. We focused more on understanding what the problem asked than memorizing formulas. Thank you to my tutor and the TestPrep team.

Balancing GMAT Focus preparation with university and work was harder than I expected. After a while, the questions started to feel much more familiar.

Lucia Fuentes
- A-Level
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Near the exam, it was clear what to keep doing and what to stop. The mocks showed where my time was actually being lost. I stopped listing facts in essays and started building an actual argument. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.
Chiara Costa
- IB Diploma
Even in a group lesson, the tutor knew where each of us stood. Breaking IB World History into smaller pieces worked much better for me. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.

I can now decide much faster when to move on from a question. Thank you to the tutor who stayed supportive until the end.
Piper Vaughn
- Digital SAT
When I started preparing for Digital SAT, I wasn't sure what order to study things in. Going back to the lesson recordings helped when I forgot a small step. The mocks showed where my time was actually being lost. Sorting mistakes after each mock changed the way I studied. I started noticing the reason for a mistake much faster. I'm glad I worked with my tutor through this process.

Everyone recommended different resources and I kept switching between them. Questions from other students often helped me as well. I became much more comfortable asking questions in class. Thanks to TestPrep for helping me stay on track.

Mauricio Alarcon
- ACT
The ACT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.
Brooke Jarvis

At the beginning, we knew very little about the ACT system as parents. Flexible scheduling helped during a demanding school year. Individual lesson time was used around our child's actual needs. The plan was adjusted when school exams became busy. A good connection with the tutor developed quite quickly. The overall experience was positive from beginning to end.
