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 knew my target, but I didn't have a realistic routine for GMAT Focus. After a while, the questions started to feel much more familiar.
Takumi Yoshida
- IB Diploma
We wanted our child to keep up with the school pace in Theory of Knowledge (TOK). The tutor's close attention to weaker areas gave us confidence. The lessons started being followed without constant reminders from us. The tutor supported regular study, not only the lesson content. Seeing the change in our child made us very happy.
Jihye Pyo
- 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
- IB Diploma
I finally understood what was going wrong in IB Economics. We could make the workload lighter during busy weeks at school or university. 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. I started noticing the reason for a mistake much faster. The preparation felt calmer than I expected.
Joel Warren
- IGCSE / GCSE
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I used the question bank regularly to return to weaker topics. My mock results gradually became more consistent. I was really happy with the lessons.
Ashleigh Wakefield
- IMAT
We wanted our child to keep up with the school pace in Logical Reasoning. Individual lesson time was used around our child's actual needs. We were pleased with the support we received.
Alan Quiroga
- AP Exams
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. I started tracking the type of mistake, not just the number of questions I completed. Source questions became easier once I noticed how small details affected the mark. It was an intense period, but it was worth it.
Lihua Dong
- SSAT
Over time, Middle Level became one of the most organized parts of my SSAT preparation. Knowing what to study reduced a lot of the stress.
Zihan Zhao
- AP Exams
The feedback I received on AP Art History was clear and practical. By the end of each lesson, I knew what I was supposed to do during the week. I began using more specific examples when explaining my ideas. I left the exam feeling that I had done what I could. I found a better balance between regular school and exam preparation. Thank you to the tutor who stayed supportive until the end.
Nuria Rojas
- GRE General
My mock scores were inconsistent, so it was hard to judge my actual level. Even in a group lesson, the tutor knew where each of us stood. Learning when to leave a hard question made a real difference to my timing. I never felt awkward asking the same thing again. The group never had more than six students, so it was easy to stay involved. I'm genuinely thankful to my tutor for being patient.
Alejandra Loyola
- A-Level
It was good to see confidence returning over time. Online lessons made it possible to continue without losing time on travel. We were pleased with the support we received.
Sloane Talbot
- PTE Academic
We wanted our child to keep up with the school pace in Repeat Sentence. Communication with the team was straightforward and our questions were answered. The overall experience was positive from beginning to end.
Facundo Arriaga
- A-Level
After my first attempt, I wanted the second round of preparation to feel more organized. I finally understood what was going wrong in A-Level Business. Going back to the lesson recordings helped when I forgot a small step. With data-heavy questions, I began reading the task before getting lost in the table. I started noticing the reason for a mistake much faster. Thank you to the tutor who stayed supportive until the end.
Poppy Mercer
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. One bad mock no longer made me want to drop the whole plan. Experiencing the exam format beforehand made test day much less stressful. Practicing in the real exam format made test day feel much less unfamiliar. I started noticing the reason for a mistake much faster. I'm genuinely thankful to my tutor for being patient.
Theo Roussel
- IGCSE / GCSE
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. The mocks showed where my time was actually being lost. I became much more comfortable asking questions in class. The preparation felt calmer than I expected.
Georgia Connolly
- Digital SAT
Our child had a clear goal but no steady study routine. Thank you sincerely to everyone involved.
Emre Gurbuz
- AP Exams
Breaking AP Calculus BC into smaller pieces worked much better for me. I started noticing the reason for a mistake much faster.
Josefina Sarmiento
- YÖS / TR-YÖS
I was close to my target, but my results changed a lot from one test to the next. I started tracking the type of mistake, not just the number of questions I completed. Lesson times could fit around school, university or work. A quick check after each answer helped me catch small mistakes. My mock results gradually became more consistent. I was really happy with the lessons.
Sloane Whitman
- GRE General
I had been studying alone, but my results stopped improving after a point. I stopped doing a huge amount one week and nothing the next. We were realistic about what could be improved in the time available. I learned not to spend the same amount of time on every line of a long text. I went into the exam much calmer than I would have before. Thank you to the tutor who stayed supportive until the end.
Karina Mazur
- ACT
The feedback I received on ACT Reading was clear and practical. I left the exam feeling that I had done what I could.
Yunfei Peng
- LSAT
After my first attempt, I wanted a calmer and more focused plan for the retake. One bad mock no longer made me want to drop the whole plan. I learned not to spend the same amount of time on every line of a long text. It was an intense period, but it was worth it.
Aylin Cakir
- IGCSE / GCSE
Over time, IGCSE Economics became one of the most organized parts of my IGCSE / GCSE preparation. I stopped doing a huge amount one week and nothing the next. My case responses became more organized and direct. Knowing what to study reduced a lot of the stress. I found a better balance between regular school and exam preparation. I'm genuinely thankful to my tutor for being patient.
Facundo Canales
- SSAT
I was doing questions for Quantitative on my own but never had a steady routine. I'm glad I worked with my tutor through this process.
Peng Tang
- A-Level
Over time, A-Level Biology became one of the most organized parts of my A-Level preparation. One bad mock no longer made me want to drop the whole plan. Knowing the topic wasn't always enough; I had to learn which information the question actually needed. My confidence improved along with the results. I wasn't trying to learn new topics at the very last minute. It was an intense period, but it was worth it.
