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!

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 :)

- GMAT Focus
I had collected too many resources without knowing when to use any of them. We didn't spend extra time on things I already knew. We focused more on understanding what the problem asked than memorizing formulas. I stopped doing a huge amount one week and nothing the next. My tutor could see my reasoning and usually found the source of an error quickly. Thank you to the tutor who stayed supportive until the end.

My mock scores were inconsistent, so it was hard to judge my actual level. Lesson times could fit around school, university or work. I started seeing shorter solutions that were easier to check under time pressure. Going back to the lesson recordings helped when I forgot a small step. My tutor could see my reasoning and usually found the source of an error quickly. I'm genuinely thankful to my tutor for being patient.

In Data Insights, timing was costing me more points than the content itself. Knowing what to study reduced a lot of the stress.
Ashleigh Baird
- GMAT Focus
I knew my target, but I didn't have a realistic routine for GMAT Focus. My tutor usually asked me to explain my thinking before stepping in. My tutor could see my reasoning and usually found the source of an error quickly. 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. Thanks to TestPrep for helping me stay on track.

- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. I finally understood what was going wrong in Data Insights. We could make the workload lighter during busy weeks at school or university. Learning when to leave a hard question made a real difference to my timing. I left the exam feeling that I had done what I could. A big thank you to my tutor for all the support :)

Lesson times could fit around school, university or work. Over time, Quantitative Reasoning became one of the most organized parts of my GMAT Focus preparation. I went into the exam much calmer than I would have before. The preparation felt calmer than I expected.

Over time, Critical Reasoning became one of the most organized parts of my GMAT Focus preparation. Balancing Quant and Verbal in the same week worked better than studying them in blocks. My confidence improved along with the results.

Phoebe Murray
- GMAT Focus
I came back to Reading Comprehension after a long break and wasn't sure where to begin. I started tracking the type of mistake, not just the number of questions I completed. Discussing why the other choices were wrong helped more than I expected. Thank you to the tutor who stayed supportive until the end.
Camila Monteiro

The feedback I received on Data Sufficiency was clear and practical. After a while, the questions started to feel much more familiar.
Serena Gallo
- GMAT Focus
After my first attempt, I wanted a calmer and more focused plan for the retake. Over time, Critical Reasoning became one of the most organized parts of my GMAT Focus preparation. By the end of each lesson, I knew what I was supposed to do during the week. Balancing Quant and Verbal in the same week worked better than studying them in blocks. I started noticing the reason for a mistake much faster. Thank you to my tutor and the TestPrep team.
Spencer Sinclair

I came back to Critical Reasoning after a long break and wasn't sure where to begin. My tutor usually asked me to explain my thinking before stepping in. Separating strategy mistakes from content gaps made progress much quicker. Thank you to the tutor who stayed supportive until the end.
Tianyu Sun
- GMAT Focus
Balancing GMAT Focus preparation with university and work was harder than I expected. After enough examples of the same question type, the repeated mistakes decreased. Discussing why the other choices were wrong helped more than I expected. By the end of each lesson, I knew what I was supposed to do during the week. Thank you to the tutor who stayed supportive until the end.

My mock scores were inconsistent, so it was hard to judge my actual level. Experiencing the exam format beforehand made test day much less stressful. I wasn't trying to learn new topics at the very last minute. Thank you to the tutor who stayed supportive until the end.
Carlo Navarro
- GMAT Focus
I knew my target, but I didn't have a realistic routine for GMAT Focus. The plan changed with my mock and homework results, so the work never felt random. I used the question bank regularly to return to weaker topics. We focused more on understanding what the problem asked than memorizing formulas. My confidence improved along with the results. I'm genuinely thankful to my tutor for being patient.

I knew my target, but I didn't have a realistic routine for GMAT Focus. Breaking Reading Comprehension into smaller pieces worked much better for me. We could make the workload lighter during busy weeks at school or university. Discussing why the other choices were wrong helped more than I expected. I wasn't trying to learn new topics at the very last minute. I'm genuinely thankful to my tutor for being patient.
Natalie Lawrence
- GMAT Focus
My mock scores were inconsistent, so it was hard to judge my actual level. My tutor usually asked me to explain my thinking before stepping in. During the intensive review, we returned to real gaps instead of restarting everything. Separating strategy mistakes from content gaps made progress much quicker. I became much more comfortable asking questions in class. Thank you to the tutor who stayed supportive until the end.

Reid Ramsey
- GMAT Focus
Breaking Data Insights into smaller pieces worked much better for me. When I got something wrong, we looked at why I chose that answer instead of only checking the solution. A quick check after each answer helped me catch small mistakes. I wasn't trying to learn new topics at the very last minute. I went into the exam much calmer than I would have before. I was really happy with the lessons.
