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!

Lesson times could fit around school, university or work. Breaking Writing Sample into smaller pieces worked much better for me. After a while, the questions started to feel much more familiar. Thanks to TestPrep for helping me stay on track.

We were realistic about what could be improved in the time available. Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. I became much more comfortable asking questions in class. Thanks to everyone who supported me.

Keeping school units and exam preparation in the same plan worked really well. Breaking AP Psychology into smaller pieces worked much better for me. There was no overnight miracle, but the progress was easy to see. A big thank you to my tutor for all the support :)

I came back to Data Analysis after a long break and wasn't sure where to begin. I finally understood what was going wrong in Data Analysis. The plan changed with my mock and homework results, so the work never felt random. Learning when to leave a hard question made a real difference to my timing. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.
Jiaqi Peng
- IB Diploma
Everyone recommended different resources and I kept switching between them. The class felt relaxed enough to ask questions without overthinking it. Past-paper questions showed me how different topics could appear together. I stopped doing a huge amount one week and nothing the next. Questions from other students often helped me as well. I was really happy with the lessons.

I finally understood what was going wrong in A-Level Mathematics. A quick check after each answer helped me catch small mistakes. My mock results gradually became more consistent.

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.

Breaking Quantitative into smaller pieces worked much better for me. I never felt awkward asking the same thing again. We focused more on understanding what the problem asked than memorizing formulas. I became much more comfortable asking questions in class. My confidence improved along with the results. Thanks to TestPrep for helping me stay on track.
Gonzalo Guerreiro
- 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.
Mariano Valdez
- IELTS Academic
In Writing Task 2, timing was costing me more points than the content itself. Breaking Writing Task 2 into smaller pieces worked much better for me. My tutor made it easy to ask questions from the first lesson. I developed a clearer way to return to the text during reading questions. I started noticing the reason for a mistake much faster. I was really happy with the lessons.
Georgia McGrath
- IELTS Academic
I chose Writing Task 1 this year and wanted to build a solid base from the beginning. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. Experiencing the exam format beforehand made test day much less stressful. We reduced the memorized phrases so my answers sounded more natural. After a while, the questions started to feel much more familiar. The preparation felt calmer than I expected.
Tessa Brennan
- YÖS / TR-YÖS
Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. My preparation became much more regular and easier to track.

We noticed that the resources kept changing during independent study. Joining lessons willingly was one of the clearest signs for us.

- GMAT Focus
Balancing GMAT Focus preparation with university and work was harder than I expected. A clear plan for the final weeks made priorities much easier to see. I started noticing the reason for a mistake much faster. A big thank you to my tutor for all the support :)

As the exam got closer, I wasn't sure what I should actually review. There was no overnight miracle, but the progress was easy to see.
Sebastian Olvera
- AP Exams
I was doing questions for AP European History on my own but never had a steady routine. The feedback I received on AP European History was clear and practical. I never felt awkward asking the same thing again. Using the mark scheme to review my own answer was surprisingly helpful. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Bastien Meunier
- IGCSE / GCSE
After my first attempt, I wanted the second round of preparation to feel more organized. I started tracking the type of mistake, not just the number of questions I completed. Having the lesson move at my pace made the process feel much easier. I became much more careful with graphs, experiments and data-based questions. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.

Balancing IELTS Academic preparation with university and work was harder than I expected. Even in a group lesson, the tutor knew where each of us stood. We reduced the memorized phrases so my answers sounded more natural. Going back to the lesson recordings helped when I forgot a small step. The class felt relaxed enough to ask questions without overthinking it. A big thank you to my tutor for all the support :)

At the beginning, we knew very little about the AP Exams system as parents. The tutor's close attention to weaker areas gave us confidence. We were happy with both the teaching and the communication.
