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!

Breaking AP Physics C: Mechanics into smaller pieces worked much better for me. After a while, the questions started to feel much more familiar.
Oliver Fraser
- TOEFL iBT
I chose Reading this year and wanted to build a solid base from the beginning. After each test, we looked beyond the score and reviewed the type of each mistake. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. The preparation felt calmer than I expected.
Daiki Nakagawa
- ACT
The ACT format felt unnecessarily confusing at first. Thank you to the tutor who stayed supportive until the end.
Vinicius Borges
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. My confidence improved along with the results.
Stefano Serra
- A-Level
I chose A-Level Business this year and wanted to build a solid base from the beginning. Experiencing the exam format beforehand made test day much less stressful. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)
Tove Kovac
- GRE General
My mock scores were inconsistent, so it was hard to judge my actual level. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. A lot of my mistakes came from rushing through the wording of the question. Thanks to everyone who supported me.
Nolan Reynolds
- AP Exams
Our child wasn't sure how to organize the preparation for AP Exams. Communication with the team was straightforward and our questions were answered. We were pleased with the support we received.
Marcus Langston
- A-Level
I was taking A-Level Chemistry at school, but getting used to the exam questions took time. The group never had more than six students, so it was easy to stay involved. I wasn't trying to learn new topics at the very last minute. The preparation felt calmer than I expected.
Mariana Alarcon
- ACT
Everyone recommended different resources and I kept switching between them. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. I learned not to spend the same amount of time on every line of a long text. I started noticing the reason for a mistake much faster. It was an intense period, but it was worth it.
Milagros Carvajal
- IGCSE / GCSE
We wanted our child to keep up with the school pace in IGCSE English as a Second Language. Including assignments and internal exams made the plan sustainable. We quickly felt that the tutor was a good match.
Shelby Finley
- AP Exams
Our child wasn't sure how to organize the preparation for AP Exams. We were happy with both the teaching and the communication.
Anouk Wagner
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor could see my reasoning and usually found the source of an error quickly. My confidence improved along with the results. Thank you to the tutor who stayed supportive until the end.
Viviana Barrera
- IB Diploma
I finally understood what was going wrong in IB Global Politics. There was no overnight miracle, but the progress was easy to see.
Elif Korkmaz
- SSAT
As the exam got closer, I wasn't sure what I should actually review. One bad mock no longer made me want to drop the whole plan. Timed work showed exactly which section was slowing me down. I was really happy with the lessons.
Erin Finlay
- YÖS / TR-YÖS
After my first attempt, I wanted the second round of preparation to feel more organized. I stopped doing a huge amount one week and nothing the next. I started seeing shorter solutions that were easier to check under time pressure. Thanks to TestPrep for helping me stay on track.
Onur Gurbuz
- IGCSE / GCSE
I was doing questions for IGCSE English Literature on my own but never had a steady routine. The group never had more than six students, so it was easy to stay involved. Discussing why the other choices were wrong helped more than I expected. I stopped doing a huge amount one week and nothing the next. Even in a group lesson, the tutor knew where each of us stood. It was an intense period, but it was worth it.
Blake Nolan
- Digital SAT
We wanted our child to keep up with the school pace in Reading & Writing. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Sota Hasegawa
- IGCSE / GCSE
I was doing questions for IGCSE Statistics on my own but never had a steady routine. My mock results gradually became more consistent.
Aditi Bedi
- TOEFL iBT
I had collected too many resources without knowing when to use any of them. My preparation became much more regular and easier to track.
Bianca Conti
- GRE General
In Analytical Writing, timing was costing me more points than the content itself. Questions from other students often helped me as well. Discussing why the other choices were wrong helped more than I expected. We could make the workload lighter during busy weeks at school or university. The group never had more than six students, so it was easy to stay involved. Thanks to everyone who supported me.
Jenna Morrow
- A-Level
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor usually asked me to explain my thinking before stepping in. The mocks showed where my time was actually being lost. Connecting examples back to the main point made my writing more consistent. I left the exam feeling that I had done what I could. I'm glad I worked with my tutor through this process.
Can Korkmaz
- GMAT Focus
Balancing GMAT Focus preparation with university and work was harder than I expected. I'm glad I worked with my tutor through this process.
Edoardo Fontana
- A-Level
Keeping up with A-Level while school was busy was harder than I expected. Breaking A-Level Computer Science into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. The lessons where I found the bug myself were the ones I remembered best. There was no overnight miracle, but the progress was easy to see. Thanks to everyone who supported me.
Kavya Bhatt
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. School assignments and internal exam dates were included in the schedule. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.
