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 was doing questions for Problem Solving & Data Analysis on my own but never had a steady routine. My tutor usually asked me to explain my thinking before stepping in. Seeing several versions of the same topic made unfamiliar questions less stressful. Thanks to everyone who supported me.

We wanted our child to keep up with the school pace in Algebra. Communication with the team was straightforward and our questions were answered. We quickly felt that the tutor was a good match.

When I started preparing for Digital SAT, I wasn't sure what order to study things in. Going back to the lesson recordings helped when I forgot a small step. The mocks showed where my time was actually being lost. Sorting mistakes after each mock changed the way I studied. I started noticing the reason for a mistake much faster. I'm glad I worked with my tutor through this process.
Kendall Brennan
- Digital SAT
Everyone recommended different resources and I kept switching between them. Questions from other students often helped me as well. I became much more comfortable asking questions in class. Thanks to TestPrep for helping me stay on track.
Manon Faure
- Digital SAT
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. We focused more on understanding what the problem asked than memorizing formulas. A big thank you to my tutor for all the support :)
Grace Spencer
- Digital SAT
I was doing questions for Advanced Math on my own but never had a steady routine. I started tracking the type of mistake, not just the number of questions I completed. I started seeing shorter solutions that were easier to check under time pressure. Thanks to everyone who supported me.
Paige Hensley
- 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.

It was good to see confidence returning over time. The tutor supported regular study, not only the lesson content. Seeing the change in our child made us very happy.
Sander Jacobs
- Digital SAT
I chose Algebra 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. Learning when to leave a hard question made a real difference to my timing. The preparation felt calmer than I expected.
Ruoxi Yu
- Digital SAT
The tutor supported regular study, not only the lesson content. Preparation looked calmer and more organized closer to the exam. Seeing the change in our child made us very happy.
Sungmin Heo
- Digital SAT
As the exam got closer, I wasn't sure what I should actually review. Over time, Problem Solving & Data Analysis became one of the most organized parts of my Digital SAT preparation. The plan changed with my mock and homework results, so the work never felt random. I started seeing shorter solutions that were easier to check under time pressure. My mock results gradually became more consistent. I'm genuinely thankful to my tutor for being patient.
Pauline Millet
- Digital SAT
I chose Expression of Ideas this year and wanted to build a solid base from the beginning. Working across different difficulty levels made new questions feel less surprising. I left the exam feeling that I had done what I could. The preparation felt calmer than I expected.
Finn Goodall
- Digital SAT
What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. I can now decide much faster when to move on from a question. Thanks to TestPrep for helping me stay on track.
Marnie Ridley
- Digital SAT
I was doing questions for Craft & Structure on my own but never had a steady routine. My mock results gradually became more consistent.
Lara Sutherland
- Digital SAT
I was taking Advanced Math at school, but getting used to the exam questions took time. Lesson times could fit around school, university or work. Seeing several versions of the same topic made unfamiliar questions less stressful. Near the exam, it was clear what to keep doing and what to stop. We didn't spend extra time on things I already knew. Thanks to TestPrep for helping me stay on track.
Andres Mercado
- Digital SAT
I was doing questions for Information & Ideas on my own but never had a steady routine. Having the lesson move at my pace made the process feel much easier. I went into the exam much calmer than I would have before. Thanks to TestPrep for helping me stay on track.
Hina Ito
- Digital SAT
Our child had a clear goal but no steady study routine. Thank you sincerely to everyone involved.
Emre Gurbuz
- Digital SAT
I was taking Information & Ideas at school, but getting used to the exam questions took time. I never felt awkward asking the same thing again. Choosing questions by topic made my practice time much more useful. Timed work showed exactly which section was slowing me down. I became much more comfortable asking questions in class. I'm genuinely thankful to my tutor for being patient.
Levi Newell
- Digital SAT
Keeping up with Digital SAT while school was busy was harder than I expected. I went into the exam much calmer than I would have before.
Riley Mallory
- Digital SAT
We noticed that the resources kept changing during independent study. With no more than six students, the tutor had time for everyone. The tutor supported regular study, not only the lesson content. Preparation looked calmer and more organized closer to the exam. We quickly felt that the tutor was a good match.
Grant Maxwell
- Digital SAT
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. My tutor could see my reasoning and usually found the source of an error quickly. Discussing why the other choices were wrong helped more than I expected. I became much more comfortable asking questions in class. Thank you to my tutor and the TestPrep team.
Juliana Arce
- Digital SAT
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. My tutor could see my reasoning and usually found the source of an error quickly. My confidence improved along with the results. Thank you to the tutor who stayed supportive until the end.
Viviana Barrera
- Digital SAT
We wanted our child to keep up with the school pace in Reading & Writing. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Sota Hasegawa
- Digital SAT
At the beginning, we knew very little about the Digital SAT system as parents. Individual lesson time was used around our child's actual needs. The tutor supported regular study, not only the lesson content. A good connection with the tutor developed quite quickly. We quickly felt that the tutor was a good match.
