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!

We wanted our child to keep up with the school pace in Reading. Being able to fit lessons around school made the process easier. We were happy with both the teaching and the communication.
Viola Grimaldi
- A-Level
The feedback I received on A-Level Physics was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. 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. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Haruto Yamamoto
- LSAT
I knew my target, but I didn't have a realistic routine for LSAT. Knowing what to study reduced a lot of the stress.
Huy Hoang
- SSAT
I was close to my target, but my results changed a lot from one test to the next. Experiencing the exam format beforehand made test day much less stressful. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
Kabir Anand
- AP Exams
The lessons started being followed without constant reminders from us. The overall experience was positive from beginning to end.
Rowan Bennett
- TOEFL iBT
The feedback I received on Listening was clear and practical. My tutor usually asked me to explain my thinking before stepping in. The writing feedback helped me stop repeating the same sentence-level errors. My mock results gradually became more consistent. My confidence improved along with the results. The preparation felt calmer than I expected.
Araya Boonmee
- YÖS / TR-YÖS
We focused more on understanding what the problem asked than memorizing formulas. Thank you to the tutor who stayed supportive until the end.
Irem Keskin
- ACT
I was close to my target, but my results changed a lot from one test to the next. The class felt relaxed enough to ask questions without overthinking it. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.
Mikkel Babic
- IB Diploma
Full-length mocks helped me get used to the real exam pace. Over time, Internal Assessment (IA) became one of the most organized parts of my IB Diploma preparation. After a while, the questions started to feel much more familiar. I was really happy with the lessons.
Nina Meier
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. I used the question bank regularly to return to weaker topics. Using the mark scheme to review my own answer was surprisingly helpful. Going back to the lesson recordings helped when I forgot a small step. I was really happy with the lessons.
Signe Solberg
- IB Diploma
Anxiety became more visible as the exam got closer. The tutor's close attention to weaker areas gave us confidence. Seeing the change in our child made us very happy.
Seulgi Kang
- IB Diploma
I finally understood what was going wrong in IB Biology. I never felt awkward asking the same thing again. Separating calculation errors from content gaps made revision more useful. There was no overnight miracle, but the progress was easy to see. My mock results gradually became more consistent. Thanks to everyone who supported me.
Miles Harcourt
- AP Exams
Keeping up with AP Exams while school was busy was harder than I expected. After enough examples of the same question type, the repeated mistakes decreased. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.
Xueying Pan
- A-Level
I finally understood what was going wrong in A-Level English Literature. I stopped choosing answers by feel and started looking for evidence in the passage. My mock results gradually became more consistent.
Kristine Mendoza
- GRE General
Full-length mocks helped me get used to the real exam pace. The feedback I received on Analytical Writing was clear and practical. My confidence improved along with the results. Thank you to the tutor who stayed supportive until the end.
Andre Borges
- A-Level
We noticed that the resources kept changing during independent study. Mistakes became something to work on rather than something to feel bad about.
Trent Banfield
- ACT
We noticed that the resources kept changing during independent study. Online lessons made it possible to continue without losing time on travel. The lessons started being followed without constant reminders from us. Topic-based question practice made study time more focused. We were able to follow the mock results regularly. Thank you sincerely to everyone involved.
Ramiro Segura
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. We focused more on understanding what the problem asked than memorizing formulas. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
Rina Miura
- A-Level
Mistakes became something to work on rather than something to feel bad about. The overall experience was positive from beginning to end.
Yuto Fujii
- AP Exams
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. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.
Lachlan Langford
- A-Level
When I started preparing for A-Level, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. I stopped choosing answers by feel and started looking for evidence in the passage. Going back to the lesson recordings helped when I forgot a small step. Questions from other students often helped me as well. I'm glad I worked with my tutor through this process.
Manuela Olvera
- ACT
I was doing questions for ACT English on my own but never had a steady routine. Thank you to the tutor who stayed supportive until the end.
Nicolas Carvajal
- AP Exams
I was taking AP English Language at school, but getting used to the exam questions took time. Breaking AP English Language into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. My written answers became shorter, clearer and easier to follow. I wasn't trying to learn new topics at the very last minute. Thanks to everyone who supported me.
Sangho Kwak
- AP Exams
The AP Exams format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. Learning when to leave a hard question made a real difference to my timing. We could make the workload lighter during busy weeks at school or university. Having the lesson move at my pace made the process feel much easier. It was an intense period, but it was worth it.
