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!

Our child wasn't sure how to organize the preparation for IB Diploma. The lessons started being followed without constant reminders from us.
Tomas Solis
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. Over time, IGCSE Mathematics became one of the most organized parts of my IGCSE / GCSE preparation. I stopped doing a huge amount one week and nothing the next. We focused more on understanding what the problem asked than memorizing formulas. My confidence improved along with the results. The preparation felt calmer than I expected.
Cristian Mena
- TOEFL iBT
At the beginning, we knew very little about the TOEFL iBT system as parents. Flexible scheduling helped during a demanding school year. Thank you sincerely to everyone involved.
Sungmin Kim
- ACT
Anxiety became more visible as the exam got closer. We quickly felt that the tutor was a good match.
Sergio Gallardo
- AP Exams
As the exam got closer, I wasn't sure what I should actually review. Over time, AP World History became one of the most organized parts of my AP Exams preparation. 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. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.
Dylan Garland
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. There was no overnight miracle, but the progress was easy to see.
Niran Raksakul
- PTE Academic
We reduced the memorized phrases so my answers sounded more natural. Thank you to my tutor and the TestPrep team.
Holly Harrison
- IB Diploma
I learned not to spend the same amount of time on every line of a long text. Thanks to TestPrep for helping me stay on track.
Catarina Barros
- IGCSE / GCSE
I was taking IGCSE Psychology at school, but getting used to the exam questions took time. 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. A big thank you to my tutor for all the support :)
Ingrid Strand
- AP Exams
The AP Exams format felt unnecessarily confusing at first. A big thank you to my tutor for all the support :)
Matilda Banfield
- ACT
The feedback I received on ACT Science was clear and practical. Separating calculation errors from content gaps made revision more useful. I became much more comfortable asking questions in class.
Luciana Carranza
- LNAT
We wanted our child to keep up with the school pace in Section A MCQ. Online lessons made it possible to continue without losing time on travel. We would recommend the program to students and families in a similar situation.
Nicolas Acosta
- A-Level
After my first attempt, I wanted the second round of preparation to feel more organized. Choosing questions by topic made my practice time much more useful. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
Abbey Tully
- A-Level
At the beginning, we knew very little about the A-Level system as parents. A good connection with the tutor developed quite quickly. The small group offered peer learning without making it hard to ask questions. The plan was adjusted when school exams became busy. We were happy with both the teaching and the communication.
Chai Dechawat
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. I never felt awkward asking the same thing again. After each test, we looked beyond the score and reviewed the type of each mistake. I became much more careful with graphs, experiments and data-based questions. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Florian Gerard
- AP Exams
Breaking AP Microeconomics into smaller pieces worked much better for me. I found a better balance between regular school and exam preparation.
Holly Lockwood
- AP Exams
After the first attempt, we looked for a calmer plan for the retake. We would recommend the program to students and families in a similar situation.
Pippa Paterson
- AP Exams
The feedback I received on AP Biology was clear and practical. I wasn't trying to learn new topics at the very last minute.
Owen Winslow
- IGCSE / GCSE
The IGCSE / GCSE format felt unnecessarily confusing at first. I left the exam feeling that I had done what I could.
Tuan Nguyen
- AP Exams
Over time, AP Psychology became one of the most organized parts of my AP Exams preparation. I learned to make a short plan before starting a long response. Knowing what to study reduced a lot of the stress.
Maja Meijer
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. Even in a group lesson, the tutor knew where each of us stood. Predicting the output helped me catch small logic errors. I never felt awkward asking the same thing again. The class felt relaxed enough to ask questions without overthinking it. The preparation felt calmer than I expected.
Afonso Correia
- AP Exams
Source questions became easier once I noticed how small details affected the mark. I was really happy with the lessons.
Noemie Picard
- PTE Academic
I was doing questions for Speaking & Writing on my own but never had a steady routine. A big thank you to my tutor for all the support :)
Karina Benes
- TOEFL iBT
