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!

I chose AP English Language this year and wanted to build a solid base from the beginning. During the intensive review, we returned to real gaps instead of restarting everything. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.

Seeing several versions of the same topic made unfamiliar questions less stressful. Thank you to the tutor who stayed supportive until the end.
Francesca Marchetti
- IGCSE / GCSE
Over time, IGCSE Art and Design became one of the most organized parts of my IGCSE / GCSE preparation. My mock results gradually became more consistent.
Alana McGrath

Breaking AP English Literature into smaller pieces worked much better for me. I left the exam feeling that I had done what I could.
Lotte Janssen
- IB Diploma
The feedback I received on IB Biology was clear and practical. Near the exam, it was clear what to keep doing and what to stop. Once I understood the reasons behind the facts, the questions felt less random. I became much more comfortable asking questions in class. I wasn't trying to learn new topics at the very last minute. I was really happy with the lessons.
Yuna Sung
- ACT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Near the exam, it was clear what to keep doing and what to stop. Past-paper questions showed me how different topics could appear together. Thank you to the tutor who stayed supportive until the end.
Gonzalo Ponce
- GMAT Focus
Over time, Reading Comprehension became one of the most organized parts of my GMAT Focus preparation. My written answers became shorter, clearer and easier to follow. I became much more comfortable asking questions in class.
Luca Leone
- Digital SAT
We weren't sure whether online lessons would be effective. Individual lesson time was used around our child's actual needs. We would recommend the program to students and families in a similar situation.
Bruno Lucero
- UCAT
Our daughter needed regular support with Situational Judgement. 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 lessons started being followed without constant reminders from us. We quickly felt that the tutor was a good match.
Raul Branco
- AP Exams
What annoyed me most was losing easy points because I rushed. Thank you to my tutor and the TestPrep team.
Meera Gowda
- IB Diploma

Merve Aydin
- A-Level
I chose A-Level History this year and wanted to build a solid base from the beginning. I wasn't trying to learn new topics at the very last minute.
Chihiro Saito
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. Even in a group lesson, the tutor knew where each of us stood. I wasn't trying to learn new topics at the very last minute. I'm glad I worked with my tutor through this process.
Isla Ritchie
- ACT
Everyone recommended different resources and I kept switching between them. I stopped doing a huge amount one week and nothing the next. Once I understood the reasons behind the facts, the questions felt less random. Thank you to the tutor who stayed supportive until the end.
Catalina Meza
- IB Diploma
After my first attempt, I wanted the second round of preparation to feel more organized. Having the lesson move at my pace made the process feel much easier. We focused more on understanding what the problem asked than memorizing formulas. My tutor usually asked me to explain my thinking before stepping in. Lesson times could fit around school, university or work. It was an intense period, but it was worth it.
Leonardo Beltran
- AP Exams
After my first attempt, I wanted the second round of preparation to feel more organized. Breaking AP Art History into smaller pieces worked much better for me. I never felt awkward asking the same thing again. Reviewing my work against the criteria changed the way I edited it. I wasn't trying to learn new topics at the very last minute. I was really happy with the lessons.
Fabio Mendes
- LNAT
Breaking Argument Analysis into smaller pieces worked much better for me. I learned not to spend the same amount of time on every line of a long text. I started noticing the reason for a mistake much faster.
Tyler Dean
- AP Exams
After my first attempt, I wanted the second round of preparation to feel more organized. My tutor made it easy to ask questions from the first lesson. My tutor could see my reasoning and usually found the source of an error quickly. Connecting examples back to the main point made my writing more consistent. I started noticing the reason for a mistake much faster. I was really happy with the lessons.
Enrico Marchetti
- AP Exams
I finally understood what was going wrong in AP European History. I wasn't trying to learn new topics at the very last minute.
Lenka Lewandowski
- A-Level
I became much more careful with graphs, experiments and data-based questions. Thank you to my tutor and the TestPrep team.
Theo Gerard
- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. My mock results gradually became more consistent.
Bailey Draper
- PTE Academic
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Going back to the lesson recordings helped when I forgot a small step. The class felt relaxed enough to ask questions without overthinking it. The writing feedback helped me stop repeating the same sentence-level errors. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.
Giulio Palmieri
- AP Exams
The AP Exams format felt unnecessarily confusing at first. Having the lesson move at my pace made the process feel much easier. Knowing the criteria from the start made the whole task less vague. My tutor made it easy to ask questions from the first lesson. We didn't spend extra time on things I already knew. It was an intense period, but it was worth it.
Jaehyun Min
- LNAT
The mocks showed where my time was actually being lost. I finally understood what was going wrong in Section A MCQ. My confidence improved along with the results. I was really happy with the lessons.
