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 finally understood what was going wrong in Mathematics. I became much more comfortable asking questions in class.
Linlin Li
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. Experiencing the exam format beforehand made test day much less stressful. Source questions became easier once I noticed how small details affected the mark. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. The mocks showed where my time was actually being lost. Thanks to TestPrep for helping me stay on track.

Levi Hawke
- A-Level
After my first attempt, I wanted the second round of preparation to feel more organized. Knowing what to study reduced a lot of the stress.
Fabien Caron
- AP Exams
Everyone recommended different resources and I kept switching between them. The group never had more than six students, so it was easy to stay involved. Knowing what to study reduced a lot of the stress. Thank you to the tutor who stayed supportive until the end.
Haeun Kim
- IB Diploma
I finally understood what was going wrong in IB Mathematics AA. We focused more on understanding what the problem asked than memorizing formulas. I started noticing the reason for a mistake much faster.
George Kirkwood
- IGCSE / GCSE
I stopped listing facts in essays and started building an actual argument. Thanks to everyone who supported me.
Zoe Fraser
- PTE Academic
Predicting the output helped me catch small logic errors. Thanks to TestPrep for helping me stay on track.
Rodrigo Tellez
- IGCSE / GCSE
Breaking IGCSE Chemistry into smaller pieces worked much better for me. I started tracking the type of mistake, not just the number of questions I completed. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I started noticing the reason for a mistake much faster. My mock results gradually became more consistent. The preparation felt calmer than I expected.
Gaia Bernardi
- IGCSE / GCSE
We noticed that the resources kept changing during independent study. Communication with the team was straightforward and our questions were answered. Past-paper work continued without falling behind in current school topics. The lessons started being followed without constant reminders from us. Flexible scheduling helped during a demanding school year. We were happy with both the teaching and the communication.
Ashleigh Vickers

Breaking Mathematics into smaller pieces worked much better for me. I went into the exam much calmer than I would have before.

- A-Level
Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thanks to everyone who supported me.
Alvaro Antunes
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. Working across different difficulty levels made new questions feel less surprising. I stopped listing facts in essays and started building an actual argument. I never felt awkward asking the same thing again. After enough examples of the same question type, the repeated mistakes decreased. Thank you to my tutor and the TestPrep team.
Phoebe Dwyer
- IGCSE / GCSE
As the exam got closer, I wasn't sure what I should actually review. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I started seeing shorter solutions that were easier to check under time pressure. I'm glad I worked with my tutor through this process.
Simone Basile
- GRE General
After my first attempt, I wanted a calmer and more focused plan for the retake. My tutor could see my reasoning and usually found the source of an error quickly. Learning when to leave a hard question made a real difference to my timing. I never felt awkward asking the same thing again. Lesson times could fit around school, university or work. Thank you to my tutor and the TestPrep team.
Mariano Tamayo
- IGCSE / GCSE
I finally understood what was going wrong in IGCSE Statistics. I started seeing shorter solutions that were easier to check under time pressure. I wasn't trying to learn new topics at the very last minute.
Hailey Foster
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. I finally understood what was going wrong in IGCSE Turkish. Going back to the lesson recordings helped when I forgot a small step. I can now decide much faster when to move on from a question. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.
Lei Cheng
- AP Exams
My case responses became more organized and direct. It was an intense period, but it was worth it.
Leif Kristensen
- IMAT
Breaking Logical Reasoning into smaller pieces worked much better for me. Separating calculation errors from content gaps made revision more useful. My preparation became much more regular and easier to track.
Tegan Pemberton
- PTE Academic
I finally understood what was going wrong in Repeat Sentence. By the end of each lesson, I knew what I was supposed to do during the week. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I started noticing the reason for a mistake much faster. Knowing what to study reduced a lot of the stress. Thanks to TestPrep for helping me stay on track.
Alan Carranza
- UCAT
I used the question bank regularly to return to weaker topics. Over time, Decision Making became one of the most organized parts of my UCAT preparation. I went into the exam much calmer than I would have before. Thanks to everyone who supported me.

I stopped listing facts in essays and started building an actual argument. The preparation felt calmer than I expected.
Celeste Chartier
- YÖS / TR-YÖS
The feedback I received on IQ & Logic was clear and practical. I stopped doing a huge amount one week and nothing the next. A quick check after each answer helped me catch small mistakes. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.
Rafaela Oliveira
- IELTS Academic
We reduced the memorized phrases so my answers sounded more natural. Thanks to TestPrep for helping me stay on track.
