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!

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.

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
- 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
- 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
- IGCSE / GCSE
After the first attempt, we looked for a calmer plan for the retake. A good connection with the tutor developed quite quickly. We thank the tutor and the TestPrep team.
Flynn Clarke

The feedback I received on IGCSE Turkish was clear and practical. I can now decide much faster when to move on from a question. I left the exam feeling that I had done what I could.
Corentin Lemoine

We didn't spend extra time on things I already knew. I finally understood what was going wrong in IGCSE Business Studies. My preparation became much more regular and easier to track. The preparation felt calmer than I expected.
Flynn Finlay

It was good to see confidence returning over time. Thank you sincerely to everyone involved.
Morgan Warren
- IGCSE / GCSE
We focused more on understanding what the problem asked than memorizing formulas. A big thank you to my tutor for all the support :)
Martin Navarrete
- IGCSE / GCSE
I was close to my target, but my results changed a lot from one test to the next. My tutor could see my reasoning and usually found the source of an error quickly. I went into the exam much calmer than I would have before. Thank you to the tutor who stayed supportive until the end.
Mette Babic
- IGCSE / GCSE
Everyone recommended different resources and I kept switching between them. Breaking IGCSE Accounting into smaller pieces worked much better for me. Near the exam, it was clear what to keep doing and what to stop. My case responses became more organized and direct. Knowing what to study reduced a lot of the stress. Thanks to everyone who supported me.
Natalie Sutton
- IGCSE / GCSE
When I started preparing for IGCSE / GCSE, I wasn't sure what order to study things in. I never felt awkward asking the same thing again. Source questions became easier once I noticed how small details affected the mark. I was really happy with the lessons.
Qiang Liang
- IGCSE / GCSE
As the exam got closer, I wasn't sure what I should actually review. During the intensive review, we returned to real gaps instead of restarting everything. Separating calculation errors from content gaps made revision more useful. I started tracking the type of mistake, not just the number of questions I completed. Focusing on past papers and mock review worked well near the exam. I was really happy with the lessons.
Chihiro Nishimura
- IGCSE / GCSE
Over time, IGCSE English as a Second Language became one of the most organized parts of my IGCSE / GCSE preparation. Going back to the lesson recordings helped when I forgot a small step. I learned not to spend the same amount of time on every line of a long text. Knowing what to study reduced a lot of the stress. There was no overnight miracle, but the progress was easy to see. I'm glad I worked with my tutor through this process.
Riley Sanderson
- IGCSE / GCSE
Keeping up with IGCSE / GCSE while school was busy was harder than I expected. One bad mock no longer made me want to drop the whole plan. I stopped choosing answers by feel and started looking for evidence in the passage. A big thank you to my tutor for all the support :)
Imogen Jarvis
- IGCSE / GCSE
Everyone recommended different resources and I kept switching between them. I found a better balance between regular school and exam preparation.
Hendrik Brandt
- IGCSE / GCSE
Mistakes became something to work on rather than something to feel bad about. A good connection with the tutor developed quite quickly. The overall experience was positive from beginning to end.
Autumn Hastings
- IGCSE / GCSE
The plan was adjusted when school exams became busy. Mistakes became something to work on rather than something to feel bad about. We would recommend the program to students and families in a similar situation.

I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Knowing what to study reduced a lot of the stress.

After the first attempt, we looked for a calmer plan for the retake. Communication with the team was straightforward and our questions were answered. Online lessons made it possible to continue without losing time on travel. Regular mocks built familiarity with the real exam pace. Joining lessons willingly was one of the clearest signs for us. The overall experience was positive from beginning to end.

We wanted our child to keep up with the school pace in IGCSE Statistics. We were pleased with the support we received.

After my first attempt, I wanted the second round of preparation to feel more organized. My tutor could see my reasoning and usually found the source of an error quickly. After a while, the questions started to feel much more familiar. I'm genuinely thankful to my tutor for being patient.
