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 son's school schedule was already very busy. Preparation looked calmer and more organized closer to the exam. We would recommend the program to students and families in a similar situation.
Natalia Santana
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. I never felt awkward asking the same thing again. Source questions became easier once I noticed how small details affected the mark. I was really happy with the lessons.
Qiang Liang
- A-Level
Our child had a clear goal but no steady study routine. The tutor's calm approach helped protect motivation during the intensive period. Joining lessons willingly was one of the clearest signs for us. The tutor supported regular study, not only the lesson content. We were pleased with the support we received.
Milagros Figueroa
- IGCSE / GCSE
As the exam got closer, I wasn't sure what I should actually review. During the intensive review, we returned to real gaps instead of restarting everything. Separating calculation errors from content gaps made revision more useful. I started tracking the type of mistake, not just the number of questions I completed. Focusing on past papers and mock review worked well near the exam. I was really happy with the lessons.
Chihiro Nishimura
- UCAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. It was an intense period, but it was worth it.
Liam Gibson
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. My mock results gradually became more consistent.
Hayden Callaghan
- IGCSE / GCSE
Over time, IGCSE English as a Second Language became one of the most organized parts of my IGCSE / GCSE preparation. Going back to the lesson recordings helped when I forgot a small step. I learned not to spend the same amount of time on every line of a long text. Knowing what to study reduced a lot of the stress. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.
Riley Sanderson
- IB Diploma
Everyone recommended different resources and I kept switching between them. I'm glad I worked with my tutor through this process.
Leif Nygard
- IB Diploma
I finally understood what was going wrong in IB English B. I stopped choosing answers by feel and started looking for evidence in the passage. There was no overnight miracle, but the progress was easy to see.
Jasmine Hume
- IGCSE / GCSE
Keeping up with IGCSE / GCSE while school was busy was harder than I expected. One bad mock no longer made me want to drop the whole plan. I stopped choosing answers by feel and started looking for evidence in the passage. A big thank you to my tutor for all the support :)
Imogen Jarvis
- IELTS Academic
Our child had a clear goal but no steady study routine. Flexible scheduling helped during a demanding school year. A good connection with the tutor developed quite quickly. The class size kept our child from disappearing into the background. We were able to follow the mock results regularly. We were pleased with the support we received.
Daniel Connolly
- IGCSE / GCSE
Everyone recommended different resources and I kept switching between them. I found a better balance between regular school and exam preparation.
Hendrik Brandt
- Digital SAT
We were able to follow the mock results regularly. The overall experience was positive from beginning to end.
Shanshan Wei
- IB Diploma
We wanted our child to keep up with the school pace in IB Computer Science. Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.
Joonho Seo
- A-Level
Our daughter needed regular support with A-Level History. The lessons started being followed without constant reminders from us.
Tahlia Hawke
- IMAT
When I started preparing for IMAT, I wasn't sure what order to study things in. Lesson times could fit around school, university or work. Once I understood the reasons behind the facts, the questions felt less random. We could make the workload lighter during busy weeks at school or university. We didn't spend extra time on things I already knew. It was an intense period, but it was worth it.
Felipe Aguirre
- IELTS Academic
After my first attempt, I wanted a calmer and more focused plan for the retake. After a while, the questions started to feel much more familiar.
Wesley Freeman
- IB Diploma
I was doing questions for IB Computer Science on my own but never had a steady routine. I stopped doing a huge amount one week and nothing the next. School assignments and internal exam dates were included in the schedule. My written code answers became much more organized. Knowing what to study reduced a lot of the stress. Thank you to my tutor and the TestPrep team.
Georgia Haines
- IMAT
Having the lesson move at my pace made the process feel much easier. Breaking General Knowledge into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.
Rodrigo Galindo
- A-Level
Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I was really happy with the lessons.
Pilar Canales
- IELTS Academic
Our son's school schedule was already very busy. The small group offered peer learning without making it hard to ask questions. We were pleased with the support we received.
Emiliano Figueroa
- IMAT
I finally understood what was going wrong in Biology. After a while, the questions started to feel much more familiar.
Ruoxi Yuan
- IELTS Academic
I had collected too many resources without knowing when to use any of them. There was no overnight miracle, but the progress was easy to see.
Arjun Sen
- IGCSE / GCSE
Mistakes became something to work on rather than something to feel bad about. A good connection with the tutor developed quite quickly. The overall experience was positive from beginning to end.
