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!

When I started preparing for AP Exams, I wasn't sure what order to study things in. Thanks to everyone who supported me.
Dewi Kusuma
- SSAT
I finally understood what was going wrong in Elementary Level. My tutor made it easy to ask questions from the first lesson. I can now decide much faster when to move on from a question. Knowing what to study reduced a lot of the stress. My mock results gradually became more consistent. I'm glad I worked with my tutor through this process.

I finally understood what was going wrong in AP European History. I learned to make a short plan before starting a long response. There was no overnight miracle, but the progress was easy to see.
Dario Ahlberg
- IB Diploma
After the first attempt, we looked for a calmer plan for the retake. Mistakes became something to work on rather than something to feel bad about. Online lessons made it possible to continue without losing time on travel. Individual lesson time was used around our child's actual needs. We were able to follow the mock results regularly. Thank you sincerely to everyone involved.
Xinyi Ma
- IB Diploma
After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in IB Visual Arts. After a while, the questions started to feel much more familiar. The preparation felt calmer than I expected.
Yui Ono
- GRE General
In Text Completion, timing was costing me more points than the content itself. The feedback I received on Text Completion was clear and practical. The plan changed with my mock and homework results, so the work never felt random. A lot of my mistakes came from rushing through the wording of the question. My confidence improved along with the results. Thanks to everyone who supported me.
Riya Bhatia
- IELTS Academic
I developed a clearer way to return to the text during reading questions. Thank you to the tutor who stayed supportive until the end.
Dev Naidu
- ACT
Over time, ACT Math became one of the most organized parts of my ACT preparation. My tutor made it easy to ask questions from the first lesson. Seeing several versions of the same topic made unfamiliar questions less stressful. I became much more comfortable asking questions in class. I found a better balance between regular school and exam preparation. The preparation felt calmer than I expected.
Mert Uzun
- TOEFL iBT
My mock scores were inconsistent, so it was hard to judge my actual level. Thank you to the tutor who stayed supportive until the end.
Lucia Vega
- Digital SAT
Keeping up with Digital SAT while school was busy was harder than I expected. The mocks showed where my time was actually being lost. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.
Frieda Kruger
- IGCSE / GCSE
After the first attempt, we looked for a calmer plan for the retake. It was good to see confidence returning over time.
Morgan Talbot
- AP Exams
I was doing questions for AP US Government on my own but never had a steady routine. The feedback I received on AP US Government was clear and practical. My tutor made it easy to ask questions from the first lesson. Connecting examples back to the main point made my writing more consistent. I left the exam feeling that I had done what I could. Thank you to the tutor who stayed supportive until the end.
Solene Tessier
- IMAT
Over time, General Knowledge became one of the most organized parts of my IMAT preparation. My tutor made it easy to ask questions from the first lesson. Source questions became easier once I noticed how small details affected the mark. I became much more comfortable asking questions in class. Knowing what to study reduced a lot of the stress. Thank you to my tutor and the TestPrep team.
Natalia Carranza
- IB Diploma
Using the mark scheme to review my own answer was surprisingly helpful. Thanks to TestPrep for helping me stay on track.
Wenjing Yang
- TOEFL iBT
As the exam got closer, I wasn't sure what I should actually review. Thank you to the tutor who stayed supportive until the end.
Pilar Arriaga
- 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. It was an intense period, but it was worth it.
Austin Delaney
- IB Diploma
I was taking IB Psychology at school, but getting used to the exam questions took time. I was really happy with the lessons.
Karina Madsen
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. The feedback I received on IB Visual Arts was clear and practical. The plan changed with my mock and homework results, so the work never felt random. Splitting time between research, making and editing kept the work manageable. My mock results gradually became more consistent. Thanks to everyone who supported me.
Hayden Sutherland
- AP Exams
When I started preparing for AP Exams, I wasn't sure what order to study things in. My preparation became much more regular and easier to track.
Yuto Takeuchi
- A-Level
We noticed that the resources kept changing during independent study. Preparation looked calmer and more organized closer to the exam. We were happy with both the teaching and the communication.
Riku Endo
- UCAT
I chose Verbal Reasoning this year and wanted to build a solid base from the beginning. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. A lot of my mistakes came from rushing through the wording of the question. My mock results gradually became more consistent. I'm glad I worked with my tutor through this process.
Federico Sala
- IB Diploma
What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. Having the lesson move at my pace made the process feel much easier. Reviewing my work against the criteria changed the way I edited it. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
Bruno Cardenas
- GMAT Focus
I knew my target, but I didn't have a realistic routine for GMAT Focus. 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. We focused more on understanding what the problem asked than memorizing formulas. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.
Hyunseok Pyo
- AP Exams
Separating calculation errors from content gaps made revision more useful. I'm glad I worked with my tutor through this process.
