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!

The feedback I received on AP Statistics was clear and practical. Seeing several versions of the same topic made unfamiliar questions less stressful. I went into the exam much calmer than I would have before.
Tuan Ly
- IB Diploma
Breaking IB Economics into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.
Jingyi Su
- IB Diploma
We wanted our child to keep up with the school pace in IB Global Politics. Returning to actual gaps instead of restarting everything saved time. The overall experience was positive from beginning to end.
Rahul Dhar
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. We could make the workload lighter during busy weeks at school or university. Timed work showed exactly which section was slowing me down. The preparation felt calmer than I expected.
Darcy Cormack
- IB Diploma
Anxiety became more visible as the exam got closer. Full-length tests showed how time was being used across the exam. Thank you sincerely to everyone involved.
Declan Menzies
- IMAT
Our daughter needed regular support with Chemistry. The small group offered peer learning without making it hard to ask questions. The lessons started being followed without constant reminders from us. It was good to see confidence returning over time. We thank the tutor and the TestPrep team.
Nina Martens
- LSAT
I had been studying alone, but my results stopped improving after a point. Having the lesson move at my pace made the process feel much easier. My written answers became shorter, clearer and easier to follow. One bad mock no longer made me want to drop the whole plan. Lesson times could fit around school, university or work. Thanks to everyone who supported me.
Jordan McMillan
- IB Diploma
I chose IB English A this year and wanted to build a solid base from the beginning. 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. Thank you to the tutor who stayed supportive until the end.
Cody Yates
- GRE General
After my first attempt, I wanted a calmer and more focused plan for the retake. 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. It was an intense period, but it was worth it.
Marine Roussel
- GRE General
After my first attempt, I wanted a calmer and more focused plan for the retake. Having the lesson move at my pace made the process feel much easier. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.
Sophie Gallagher
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. We didn't spend extra time on things I already knew. I stopped choosing answers by feel and started looking for evidence in the passage. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. A big thank you to my tutor for all the support :)
Lauren Callahan
- IGCSE / GCSE
After enough examples of the same question type, the repeated mistakes decreased. I finally understood what was going wrong in IGCSE English. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.
Emilia Tamayo
- IGCSE / GCSE
Breaking IGCSE Geography into smaller pieces worked much better for me. I learned to make a short plan before starting a long response. My mock results gradually became more consistent.
Quang Ngo
- AP Exams
My written code answers became much more organized. Thanks to TestPrep for helping me stay on track.
Maeve Webster
- A-Level
Lesson times could fit around school, university or work. The feedback I received on A-Level Accounting was clear and practical. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
Leticia Santos
- SSAT
I was doing questions for Upper Level on my own but never had a steady routine. I became much more comfortable asking questions in class.
Erdem Duman
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. One bad mock no longer made me want to drop the whole plan. After enough examples of the same question type, the repeated mistakes decreased. Seeing several versions of the same topic made unfamiliar questions less stressful. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.
Nicha Chaisiri
- IGCSE / GCSE
I was taking IGCSE Art and Design at school, but getting used to the exam questions took time. We didn't spend extra time on things I already knew. I began using more specific examples when explaining my ideas. I never felt awkward asking the same thing again. Thank you to my tutor and the TestPrep team.
Naoki Tamura
- IB Diploma
At the beginning, we knew very little about the IB Diploma system as parents. It was good to see confidence returning over time. Full-length tests showed how time was being used across the exam. The plan was adjusted when school exams became busy. Seeing the change in our child made us very happy.
Fraser Hargreaves
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
Chelsea Norris
- TOEFL iBT
During the intensive review, we returned to real gaps instead of restarting everything. Over time, Integrated Tasks became one of the most organized parts of my TOEFL iBT preparation. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.
Dong Deng
- IGCSE / GCSE
The mocks showed where my time was actually being lost. Over time, IGCSE Combined Science became one of the most organized parts of my IGCSE / GCSE preparation. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Skye McIntyre
- LNAT
A good connection with the tutor developed quite quickly. The lessons started being followed without constant reminders from us. The overall experience was positive from beginning to end.
Sneha Tandon
- AP Exams
I chose AP Human Geography this year and wanted to build a solid base from the beginning. Going back to the lesson recordings helped when I forgot a small step. I stopped listing facts in essays and started building an actual argument. Thank you to the tutor who stayed supportive until the end.
