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!

As the exam got closer, I wasn't sure what I should actually review. Thanks to TestPrep for helping me stay on track.

Everyone recommended different resources and I kept switching between them. Over time, IB Mathematics AI became one of the most organized parts of my IB Diploma preparation. The plan changed with my mock and homework results, so the work never felt random. We focused more on understanding what the problem asked than memorizing formulas. After a while, the questions started to feel much more familiar. Thank you to the tutor who stayed supportive until the end.

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.

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.

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.

I realized that choosing a topic, researching and revising each needed its own deadline. It was an intense period, but it was worth it.

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
- 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.

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
- IB Diploma
The feedback I received on IB Economics was clear and practical. Near the exam, it was clear what to keep doing and what to stop. With data-heavy questions, I began reading the task before getting lost in the table. I found a better balance between regular school and exam preparation. Thank you to my tutor and the TestPrep team.
Nils Prochazka
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. I used the question bank regularly to return to weaker topics. Connecting examples back to the main point made my writing more consistent. By the end of each lesson, I knew what I was supposed to do during the week. After enough examples of the same question type, the repeated mistakes decreased. It was an intense period, but it was worth it.

I was doing questions for IB Turkish A on my own but never had a steady routine. I wasn't trying to learn new topics at the very last minute.
Aisling Caldwell
- IB Diploma
I chose Theory of Knowledge (TOK) this year and wanted to build a solid base from the beginning. I never felt awkward asking the same thing again. The feedback helped me improve my own work without writing it for me. Thank you to my tutor and the TestPrep team.
Flynn Donovan
- IB Diploma
Everyone recommended different resources and I kept switching between them. I started tracking the type of mistake, not just the number of questions I completed. The class felt relaxed enough to ask questions without overthinking it. I stopped listing facts in essays and started building an actual argument. After a while, the questions started to feel much more familiar. I was really happy with the lessons.
Marcos Barros
- IB Diploma
Over time, IB Psychology became one of the most organized parts of my IB Diploma preparation. I learned to make a short plan before starting a long response. I became much more comfortable asking questions in class.

Breaking Extended Essay (EE) into smaller pieces worked much better for me. Knowing the criteria from the start made the whole task less vague. I found a better balance between regular school and exam preparation.
Elif Gunes
- IB Diploma
I was doing questions for IB ESS on my own but never had a steady routine. By the end of each lesson, I knew what I was supposed to do during the week. We didn't spend extra time on things I already knew. Once I understood the reasons behind the facts, the questions felt less random. My confidence improved along with the results. A big thank you to my tutor for all the support :)
Cassidy Coleman
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.

After my first attempt, I wanted the second round of preparation to feel more organized. There was no overnight miracle, but the progress was easy to see.
Annika Kral

We wanted our child to keep up with the school pace in IB Philosophy. Online lessons made it possible to continue without losing time on travel.
Aditya Desai
- IB Diploma
Breaking IB Geography into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I learned to make a short plan before starting a long response. I became much more comfortable asking questions in class. I went into the exam much calmer than I would have before. Thanks to everyone who supported me.

I finally understood what was going wrong in Extended Essay (EE). Knowing what to study reduced a lot of the stress.
