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 feedback I received on IGCSE Accounting was clear and practical. My tutor made it easy to ask questions from the first lesson. Separating strategy mistakes from content gaps made progress much quicker. Knowing what to study reduced a lot of the stress. After a while, the questions started to feel much more familiar. Thank you to my tutor and the TestPrep team.

A clear plan for the final weeks made priorities much easier to see. Breaking Listening into smaller pieces worked much better for me. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.
Amanda Silveira
- PTE Academic
The PTE Academic format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. I wasn't trying to learn new topics at the very last minute. Thanks to TestPrep for helping me stay on track.
Elena Sequeira
- A-Level
Learning when to leave a hard question made a real difference to my timing. Thank you to my tutor and the TestPrep team.
Danilo Machado
- IB Diploma
I was taking IB Global Politics at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. I stopped listing facts in essays and started building an actual argument. I was really happy with the lessons.
Bruno Pinheiro
- IMAT
After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. Thank you sincerely to everyone involved.

Over time, IB Mathematics AI became one of the most organized parts of my IB Diploma preparation. There was no overnight miracle, but the progress was easy to see.
Anan Srisai
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. After each test, we looked beyond the score and reviewed the type of each mistake. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.
Mafalda Correia
- IGCSE / GCSE
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. After each test, we looked beyond the score and reviewed the type of each mistake. Splitting time between research, making and editing kept the work manageable. My tutor usually asked me to explain my thinking before stepping in. Experiencing the exam format beforehand made test day much less stressful. The preparation felt calmer than I expected.
Avery Donovan
- AP Exams
After each test, we looked beyond the score and reviewed the type of each mistake. Over time, AP Physics C: Mechanics became one of the most organized parts of my AP Exams preparation. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Ayaka Murakami
- IB Diploma
Keeping up with IB Diploma while school was busy was harder than I expected. Having the lesson move at my pace made the process feel much easier. 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. We didn't spend extra time on things I already knew. Thank you to the tutor who stayed supportive until the end.
Bruno Espinoza
- PTE Academic
After enough examples of the same question type, the repeated mistakes decreased. Breaking Write from Dictation into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
Zoe Rawson
- AP Exams
I was doing questions for AP English Language on my own but never had a steady routine. We could make the workload lighter during busy weeks at school or university. My written answers became shorter, clearer and easier to follow. Thanks to everyone who supported me.
Lei Shen
- IGCSE / GCSE
The feedback I received on IGCSE Combined Science was clear and practical. Separating calculation errors from content gaps made revision more useful. I became much more comfortable asking questions in class.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I found a better balance between regular school and exam preparation.
Matilde Esteves
- YÖS / TR-YÖS
The group never had more than six students, so it was easy to stay involved. I finally understood what was going wrong in Time Management. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)
Felipe Montalvo
- 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. Sorting mistakes after each mock changed the way I studied. Thanks to everyone who supported me.
Ewan Connolly
- Digital SAT
Over time, Reading & Writing became one of the most organized parts of my Digital SAT preparation. 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.
Elena Vitale
- Digital SAT
I chose Reading & Writing this year and wanted to build a solid base from the beginning. Full-length mocks helped me get used to the real exam pace. My written answers became shorter, clearer and easier to follow. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. After each test, we looked beyond the score and reviewed the type of each mistake. A big thank you to my tutor for all the support :)
Nicolas Zuniga
- IMAT
The feedback I received on Physics was clear and practical. I became much more careful with graphs, experiments and data-based questions. My confidence improved along with the results.
Martina Leone
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. I finally understood what was going wrong in IGCSE Biology. We could make the workload lighter during busy weeks at school or university. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track. Thank you to my tutor and the TestPrep team.
Gabriel Correia
- IGCSE / GCSE
Mistakes became something to work on rather than something to feel bad about. Online lessons made it possible to continue without losing time on travel. We thank the tutor and the TestPrep team.
Celeste Delorme
- GMAT Focus
Breaking Critical Reasoning into smaller pieces worked much better for me. Going back to the lesson recordings helped when I forgot a small step. Separating strategy mistakes from content gaps made progress much quicker. My mock results gradually became more consistent. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
