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!

I chose AP Calculus BC this year and wanted to build a solid base from the beginning. I started noticing the reason for a mistake much faster.
Valentina Beltran
- Digital SAT
After my first attempt, I wanted the second round of preparation to feel more organized. We could make the workload lighter during busy weeks at school or university. We were realistic about what could be improved in the time available. We focused more on understanding what the problem asked than memorizing formulas. I started noticing the reason for a mistake much faster. Thanks to TestPrep for helping me stay on track.
Mauricio Urrutia
- PTE Academic
I learned not to lose the rest of a listening task because I missed one word. A big thank you to my tutor for all the support :)
Camden Nichols
- IB Diploma
I was close to my target, but my results changed a lot from one test to the next. One bad mock no longer made me want to drop the whole plan. Focusing on past papers and mock review worked well near the exam. Separating strategy mistakes from content gaps made progress much quicker. I started noticing the reason for a mistake much faster. Thanks to everyone who supported me.
Cody Wakefield
- IB Diploma
Everyone recommended different resources and I kept switching between them. Thanks to everyone who supported me.

The lessons started being followed without constant reminders from us. It was good to see confidence returning over time. We quickly felt that the tutor was a good match.
Victor Santana
- GRE General
After my first attempt, I wanted a calmer and more focused plan for the retake. Near the exam, it was clear what to keep doing and what to stop. Full-length mocks helped me get used to the real exam pace. I started seeing shorter solutions that were easier to check under time pressure. My confidence improved along with the results. Thanks to everyone who supported me.
Hugo Lambert
- GRE General
In Text Completion, timing was costing me more points than the content itself. The plan changed with my mock and homework results, so the work never felt random. My tutor could see my reasoning and usually found the source of an error quickly. My written answers became shorter, clearer and easier to follow. I found a better balance between regular school and exam preparation. Thanks to everyone who supported me.
Lan Do
- PTE Academic
Breaking Speaking & Writing into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. After a while, the questions started to feel much more familiar. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Xinyi Pan
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. My tutor could see my reasoning and usually found the source of an error quickly. I became much more comfortable asking questions in class. I was really happy with the lessons.
Amandine Perrin
- IB Diploma
The feedback I received on IB World History was clear and practical. Source questions became easier once I noticed how small details affected the mark. I left the exam feeling that I had done what I could.

Online lessons made it possible to continue without losing time on travel. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.
Huong Dang
- Digital SAT
I chose Reading & Writing this year and wanted to build a solid base from the beginning. Near the exam, it was clear what to keep doing and what to stop.

Tobias VanDijk
- ACT

Lars Bos
- ACT

Alper Ozturk
- IGCSE / GCSE
Over time, IGCSE Psychology became one of the most organized parts of my IGCSE / GCSE preparation. I wasn't trying to learn new topics at the very last minute.
Marco Rinaldi

Eunji Seo
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. My tutor usually asked me to explain my thinking before stepping in. We didn't spend extra time on things I already knew. Balancing Quant and Verbal in the same week worked better than studying them in blocks. I left the exam feeling that I had done what I could. It was an intense period, but it was worth it.
Arif Siregar
- Digital SAT
The Digital SAT format felt unnecessarily confusing at first. Near the exam, it was clear what to keep doing and what to stop. The class felt relaxed enough to ask questions without overthinking it. I started seeing shorter solutions that were easier to check under time pressure. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.

Keeping up with IB Diploma while school was busy was harder than I expected. After enough examples of the same question type, the repeated mistakes decreased. My confidence improved along with the results. I was really happy with the lessons.
Thomas Redmond
- A-Level
Over time, A-Level Economics became one of the most organized parts of my A-Level preparation. Balancing Quant and Verbal in the same week worked better than studying them in blocks. My mock results gradually became more consistent.
