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. I stopped doing a huge amount one week and nothing the next. Using the mark scheme to review my own answer was surprisingly helpful. Thanks to TestPrep for helping me stay on track.

After the first attempt, we looked for a calmer plan for the retake. The plan was adjusted when school exams became busy. Returning to actual gaps instead of restarting everything saved time. We were able to follow the mock results regularly. Preparation looked calmer and more organized closer to the exam. The overall experience was positive from beginning to end.

It was good to see confidence returning over time. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.

After my first attempt, I wanted the second round of preparation to feel more organized. I finally understood what was going wrong in A-Level Business. Going back to the lesson recordings helped when I forgot a small step. With data-heavy questions, I began reading the task before getting lost in the table. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.

Over time, A-Level Biology became one of the most organized parts of my A-Level preparation. One bad mock no longer made me want to drop the whole plan. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. My confidence improved along with the results. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.

When I started preparing for A-Level, I wasn't sure what order to study things in. I left the exam feeling that I had done what I could.

Everyone recommended different resources and I kept switching between them. I never felt awkward asking the same thing again. Predicting the output helped me catch small logic errors. I'm glad I worked with my tutor through this process.

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 :)

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
- 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.

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.

I was taking A-Level Physics at school, but getting used to the exam questions took time. Experiencing the exam format beforehand made test day much less stressful. I became much more careful with graphs, experiments and data-based questions. My tutor usually asked me to explain my thinking before stepping in. Thank you to my tutor and the TestPrep team.

Our daughter needed regular support with A-Level Sociology. The lessons started being followed without constant reminders from us. We would recommend the program to students and families in a similar situation.

I understood that the portfolio needed to show the process, not only the finished piece. I'm genuinely thankful to my tutor for being patient.

Over time, A-Level Further Mathematics became one of the most organized parts of my A-Level preparation. A quick check after each answer helped me catch small mistakes. I left the exam feeling that I had done what I could.
Evie Whitlam
- A-Level
The feedback I received on A-Level Psychology was clear and practical. 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. Knowing what to study reduced a lot of the stress. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.

Mert Akbulut

Breaking A-Level Business into smaller pieces worked much better for me. The plan changed with my mock and homework results, so the work never felt random. I learned to separate the information needed for a decision from the extra detail. There was no overnight miracle, but the progress was easy to see. After a while, the questions started to feel much more familiar. I was really happy with the lessons.
Hendrik Kuiper
- A-Level
I was doing questions for A-Level History on my own but never had a steady routine. I never felt awkward asking the same thing again. I stopped listing facts in essays and started building an actual argument. Thank you to my tutor and the TestPrep team.

Our daughter needed regular support with A-Level Chemistry. The small group offered peer learning without making it hard to ask questions. Flexible scheduling helped during a demanding school year.

The feedback I received on A-Level Physics was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. I started noticing the reason for a mistake much faster. After a while, the questions started to feel much more familiar. It was an intense period, but it was worth it.

I finally understood what was going wrong in A-Level English Literature. I stopped choosing answers by feel and started looking for evidence in the passage. My mock results gradually became more consistent.
