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!

Keeping up with A-Level while school was busy was harder than I expected. Having the lesson move at my pace made the process feel much easier. There was no overnight miracle, but the progress was easy to see. I was really happy with the lessons.
Tomas Godoy
- LNAT
The feedback I received on Section B Essay was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. Discussing why the other choices were wrong helped more than I expected. There was no overnight miracle, but the progress was easy to see. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.
Lauren Langley
- PTE Academic
Our child wasn't sure how to organize the preparation for PTE Academic. Seeing the change in our child made us very happy.
James Gallagher
- IGCSE / GCSE
I was taking IGCSE Accounting at school, but getting used to the exam questions took time. The plan changed with my mock and homework results, so the work never felt random. Choosing questions by topic made my practice time much more useful. With data-heavy questions, I began reading the task before getting lost in the table. I found a better balance between regular school and exam preparation. It was an intense period, but it was worth it.
Javier Cunha
- YÖS / TR-YÖS
Breaking Mathematics into smaller pieces worked much better for me. My tutor usually asked me to explain my thinking before stepping in. Learning when to leave a hard question made a real difference to my timing. I started noticing the reason for a mistake much faster. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
Lorena Lemus
- UCAT
Over time, Decision Making became one of the most organized parts of my UCAT preparation. There was no overnight miracle, but the progress was easy to see.
Arjun Bose
- IGCSE / GCSE
The feedback I received on IGCSE Biology was clear and practical. Once I understood the reasons behind the facts, the questions felt less random. After a while, the questions started to feel much more familiar.
Johanna Lange
- A-Level
I was close to my target, but my results changed a lot from one test to the next. Even in a group lesson, the tutor knew where each of us stood. Past-paper questions showed me how different topics could appear together. We could make the workload lighter during busy weeks at school or university. Questions from other students often helped me as well. The preparation felt calmer than I expected.
Alfie Webster
- SSAT
Our child wasn't sure how to organize the preparation for SSAT. The small group offered peer learning without making it hard to ask questions. Mistakes became something to work on rather than something to feel bad about. Preparation looked calmer and more organized closer to the exam. We would recommend the program to students and families in a similar situation.
Bailey Kirk
- Digital SAT
I was taking SAT Math 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. I started seeing shorter solutions that were easier to check under time pressure. Going back to the lesson recordings helped when I forgot a small step. It was an intense period, but it was worth it.
Noelia Segura
- PTE Academic
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. By the end of each lesson, I knew what I was supposed to do during the week. The writing feedback helped me stop repeating the same sentence-level errors. A big thank you to my tutor for all the support :)
Ruby Gibson
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. A quick check after each answer helped me catch small mistakes. By the end of each lesson, I knew what I was supposed to do during the week. Thanks to TestPrep for helping me stay on track.
Finn Brandt
- IB Diploma
I was taking Theory of Knowledge (TOK) at school, but getting used to the exam questions took time. I finally understood what was going wrong in Theory of Knowledge (TOK). I started tracking the type of mistake, not just the number of questions I completed. Knowing the criteria from the start made the whole task less vague. I found a better balance between regular school and exam preparation. The preparation felt calmer than I expected.
Carter Brooks
- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. Lesson times could fit around school, university or work. I started seeing shorter solutions that were easier to check under time pressure. Going back to the lesson recordings helped when I forgot a small step. My tutor could see my reasoning and usually found the source of an error quickly. I'm genuinely thankful to my tutor for being patient.
Alessio Piras
- Digital SAT
A quick check after each answer helped me catch small mistakes. Thank you to the tutor who stayed supportive until the end.
Hilal Kilic
- Digital SAT
After my first attempt, I wanted the second round of preparation to feel more organized. Going back to the lesson recordings helped when I forgot a small step. We didn't spend extra time on things I already knew. Learning when to leave a hard question made a real difference to my timing. I found a better balance between regular school and exam preparation. The preparation felt calmer than I expected.
Esteban Varela
- A-Level
The A-Level format felt unnecessarily confusing at first. My tutor made it easy to ask questions from the first lesson. My written code answers became much more organized. I was really happy with the lessons.
Isla Sanderson
- AP Exams
I was close to my target, but my results changed a lot from one test to the next. Breaking AP Physics C: E&M into smaller pieces worked much better for me. One bad mock no longer made me want to drop the whole plan. I became much more careful with graphs, experiments and data-based questions. My mock results gradually became more consistent. It was an intense period, but it was worth it.
Franco Urrutia
- GRE General
I knew my target, but I didn't have a realistic routine for GRE General. We didn't spend extra time on things I already knew. Discussing why the other choices were wrong helped more than I expected. By the end of each lesson, I knew what I was supposed to do during the week. My tutor could see my reasoning and usually found the source of an error quickly. I was really happy with the lessons.
Riya Grover
- YÖS / TR-YÖS
A good connection with the tutor developed quite quickly. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Nils Ahlberg
- A-Level
I was taking A-Level Sociology at school, but getting used to the exam questions took time. We could make the workload lighter during busy weeks at school or university. Using the mark scheme to review my own answer was surprisingly helpful. The preparation felt calmer than I expected.
Aditya Rao
- IELTS Academic
Breaking Writing Task 1 into smaller pieces worked much better for me. We reduced the memorized phrases so my answers sounded more natural. There was no overnight miracle, but the progress was easy to see.
Greta Janssen
- SSAT
The SSAT format felt unnecessarily confusing at first. There was no overnight miracle, but the progress was easy to see.
Yerin Jin
- IGCSE / GCSE
As the exam got closer, I wasn't sure what I should actually review. Choosing questions by topic made my practice time much more useful. Discussing why the other choices were wrong helped more than I expected. The plan changed with my mock and homework results, so the work never felt random. I used the question bank regularly to return to weaker topics. Thank you to the tutor who stayed supportive until the end.
