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!

Balancing IELTS Academic preparation with university and work was harder than I expected. Over time, Writing Task 2 became one of the most organized parts of my IELTS Academic preparation. Near the exam, it was clear what to keep doing and what to stop. It took time to stop worrying about mistakes in speaking practice, but the lessons felt relaxed. My preparation became much more regular and easier to track. It was an intense period, but it was worth it.

I was doing questions for Speaking & Writing on my own but never had a steady routine. Lesson times could fit around school, university or work. I went into the exam much calmer than I would have before. I was really happy with the lessons.

The feedback helped me improve my own work without writing it for me. Thanks to TestPrep for helping me stay on track.

After the first attempt, we looked for a calmer plan for the retake. Being able to fit lessons around school made the process easier. Seeing the change in our child made us very happy.
Nils Bergman
- IELTS Academic
Over time, Academic Reading became one of the most organized parts of my IELTS Academic preparation. I started tracking the type of mistake, not just the number of questions I completed. The writing feedback helped me stop repeating the same sentence-level errors. My confidence improved along with the results. I left the exam feeling that I had done what I could. It was an intense period, but it was worth it.
Henrique Garcia
- AP Exams
I was close to my target, but my results changed a lot from one test to the next. After enough examples of the same question type, the repeated mistakes decreased. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.
Mikkel Svoboda
- SSAT
The feedback I received on Reading was clear and practical. A lot of my mistakes came from rushing through the wording of the question. My confidence improved along with the results.
Miguel Campos
- AP Exams
As the exam got closer, I wasn't sure what I should actually review. I never felt awkward asking the same thing again. My written code answers became much more organized. I'm glad I worked with my tutor through this process.
Minji Yoon
- IB Diploma
What annoyed me most was losing easy points because I rushed. I started tracking the type of mistake, not just the number of questions I completed. Connecting examples back to the main point made my writing more consistent. Thank you to my tutor and the TestPrep team.
Pinar Korkmaz
- IB Diploma
We noticed that the resources kept changing during independent study. It was good to see confidence returning over time. Individual lesson time was used around our child's actual needs. Preparation looked calmer and more organized closer to the exam. We were able to follow the mock results regularly. We quickly felt that the tutor was a good match.

Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in AP English Language. My preparation became much more regular and easier to track. I'm glad I worked with my tutor through this process.

I chose IB Mathematics AI this year and wanted to build a solid base from the beginning. Having the lesson move at my pace made the process feel much easier. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.
Lorenzo Rizzo
- A-Level
Everyone recommended different resources and I kept switching between them. The group never had more than six students, so it was easy to stay involved. Past-paper questions showed me how different topics could appear together. My tutor usually asked me to explain my thinking before stepping in. Questions from other students often helped me as well. I'm glad I worked with my tutor through this process.
Gonzalo Bustos
- IB Diploma
The feedback I received on IB English B was clear and practical. Going back to the lesson recordings helped when I forgot a small step. My written answers became shorter, clearer and easier to follow. I wasn't trying to learn new topics at the very last minute. My mock results gradually became more consistent. The preparation felt calmer than I expected.
Ayaka Yoshida
- IB Diploma
I finally understood what was going wrong in IB TITC. Near the exam, it was clear what to keep doing and what to stop. I worked on keeping a steady pace instead of rushing the easy questions. My confidence improved along with the results. I went into the exam much calmer than I would have before. I'm genuinely thankful to my tutor for being patient.
Isabela Godoy
- Digital SAT
We weren't sure whether online lessons would be effective. Communication with the team was straightforward and our questions were answered. We would recommend the program to students and families in a similar situation.
Natalia Gomes
- SSAT
I was taking Elementary Level at school, but getting used to the exam questions took time. By the end of each lesson, I knew what I was supposed to do during the week. The mocks showed where my time was actually being lost. Sorting mistakes after each mock changed the way I studied. My confidence improved along with the results. I'm glad I worked with my tutor through this process.

The feedback I received on Writing 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. I found a better balance between regular school and exam preparation. I left the exam feeling that I had done what I could. Thanks to everyone who supported me.

A good connection with the tutor developed quite quickly. The plan was adjusted when school exams became busy. We were pleased with the support we received.

The tutor supported regular study, not only the lesson content. We would recommend the program to students and families in a similar situation.
Youngmin Han
- IMAT
When I started preparing for IMAT, I wasn't sure what order to study things in. I left the exam feeling that I had done what I could.
Keira Garland
- AP Exams
The feedback I received on AP Research was clear and practical. One bad mock no longer made me want to drop the whole plan. Breaking the draft into smaller parts made it feel much more doable. I started noticing the reason for a mistake much faster. I became much more comfortable asking questions in class. It was an intense period, but it was worth it.
Maya Graham
- AP Exams
I understood that the portfolio needed to show the process, not only the finished piece. Thank you to my tutor and the TestPrep team.
