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 was taking Algebra at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. Seeing several versions of the same topic made unfamiliar questions less stressful. The preparation felt calmer than I expected.

We weren't sure whether online lessons would be effective. Being able to fit lessons around school made the process easier. We were pleased with the support we received.

After my first attempt, I wanted the second round of preparation to feel more organized. Breaking AP Computer Science Principles into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. My written code answers became much more organized. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.

I chose Chemistry this year and wanted to build a solid base from the beginning. The feedback I received on Chemistry was clear and practical. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

I was taking Bluebook adaptif modüller at school, but getting used to the exam questions took time. My tutor could see my reasoning and usually found the source of an error quickly. My mock results gradually became more consistent. A big thank you to my tutor for all the support :)
Gaia Conti
- A-Level
Everyone recommended different resources and I kept switching between them. Focusing on past papers and mock review worked well near the exam. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)
Brodie Kearney
- AP Exams
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Going back to the lesson recordings helped when I forgot a small step. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. Thanks to everyone who supported me.
Vivek Mukherjee
- GMAT Focus
A quick check after each answer helped me catch small mistakes. Thank you to my tutor and the TestPrep team.
Kyungsoo Guk
- GRE General
Balancing GRE General preparation with university and work was harder than I expected. The preparation felt calmer than I expected.
Zihan Cheng
- IGCSE / GCSE
Full-length mocks helped me get used to the real exam pace. I finally understood what was going wrong in IGCSE Chemistry. I left the exam feeling that I had done what I could. I was really happy with the lessons.

The plan was adjusted when school exams became busy. Communication with the team was straightforward and our questions were answered. Thank you sincerely to everyone involved.

We wanted our child to keep up with the school pace in Biology. We would recommend the program to students and families in a similar situation.

- A-Level
I was taking A-Level Art and Design at school, but getting used to the exam questions took time. My confidence improved along with the results.
Naina Hegde
- IELTS Academic
The IELTS Academic format felt unnecessarily confusing at first. I used the question bank regularly to return to weaker topics. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Bruno Correia
- IB Diploma
I was taking Extended Essay (EE) at school, but getting used to the exam questions took time. I found a better balance between regular school and exam preparation.

Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in Logical Reasoning. My mock results gradually became more consistent. I was really happy with the lessons.
Gabriela Quiroga

We weren't sure whether online lessons would be effective. The tutor's close attention to weaker areas gave us confidence. We quickly felt that the tutor was a good match.
Minseok Song
- A-Level
What annoyed me most was losing easy points because I rushed. I finally understood what was going wrong in A-Level Art and Design. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. I understood that the portfolio needed to show the process, not only the finished piece. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Lara Vogel
- ACT
When I started preparing for ACT, I wasn't sure what order to study things in. The plan changed with my mock and homework results, so the work never felt random. Once I understood the reasons behind the facts, the questions felt less random. Thank you to the tutor who stayed supportive until the end.
Maddison Pemberton
- LNAT
After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in Reading Comprehension. There was no overnight miracle, but the progress was easy to see. Thank you to the tutor who stayed supportive until the end.
Nico Vos
- AP Exams
Our child had a clear goal but no steady study routine. Preparation looked calmer and more organized closer to the exam. Being able to fit lessons around school made the process easier. The tutor supported regular study, not only the lesson content. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.
Fiona Bennett
- ACT
Over time, ACT Science became one of the most organized parts of my ACT preparation. My tutor usually asked me to explain my thinking before stepping in. Once I understood the reasons behind the facts, the questions felt less random. I became much more comfortable asking questions in class. I found a better balance between regular school and exam preparation. I was really happy with the lessons.

It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. I'm genuinely thankful to my tutor for being patient.
