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!

What annoyed me most was losing easy points because I rushed. 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. Thanks to everyone who supported me.

Once I understood the reasons behind the facts, the questions felt less random. I was really happy with the lessons.

Keeping up with IB Diploma while school was busy was harder than I expected. Going back to the lesson recordings helped when I forgot a small step. A quick check after each answer helped me catch small mistakes. Thank you to my tutor and the TestPrep team.

The feedback I received on IB Global Politics was clear and practical. Using the mark scheme to review my own answer was surprisingly helpful. I started noticing the reason for a mistake much faster.
Lucie Fontaine
- IB Diploma
The IB Diploma format felt unnecessarily confusing at first. Lesson times could fit around school, university or work. Source questions became easier once I noticed how small details affected the mark. I never felt awkward asking the same thing again. We didn't spend extra time on things I already knew. It was an intense period, but it was worth it.

I chose IB World History this year and wanted to build a solid base from the beginning. Keeping school units and exam preparation in the same plan worked really well. I went into the exam much calmer than I would have before. The preparation felt calmer than I expected.
Kenta Maeda
- IB Diploma
I wasn't starting from zero, but the same mistakes kept showing up in my mocks. Working across different difficulty levels made new questions feel less surprising. A quick check after each answer helped me catch small mistakes. My tutor made it easy to ask questions from the first lesson. After enough examples of the same question type, the repeated mistakes decreased. The preparation felt calmer than I expected.

Focusing on past papers and mock review worked well near the exam. Over time, Internal Assessment (IA) became one of the most organized parts of my IB Diploma preparation. Knowing what to study reduced a lot of the stress. I'm glad I worked with my tutor through this process.
Rasmus Ahlberg
- IB Diploma
Over time, IB Business Management became one of the most organized parts of my IB Diploma preparation. 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.
Chloe Atkins
- IB Diploma
When I started preparing for IB Diploma, I wasn't sure what order to study things in. The group never had more than six students, so it was easy to stay involved. A lot of my mistakes came from rushing through the wording of the question. I stopped doing a huge amount one week and nothing the next. The class felt relaxed enough to ask questions without overthinking it. Thanks to everyone who supported me.

The IB Diploma format felt unnecessarily confusing at first. My tutor made it easy to ask questions from the first lesson. We balanced current school topics with past-paper practice. I learned to make a short plan before starting a long response. There was no overnight miracle, but the progress was easy to see. The preparation felt calmer than I expected.
Lachlan Menzies

Our son's school schedule was already very busy. The tutor's close attention to weaker areas gave us confidence. The overall experience was positive from beginning to end.
Lijuan Wu

Having the lesson move at my pace made the process feel much easier. I finally understood what was going wrong in IB Philosophy. My confidence improved along with the results. The preparation felt calmer than I expected.
Bianca Martins
- IB Diploma
After the first attempt, we looked for a calmer plan for the retake. Mistakes became something to work on rather than something to feel bad about. Online lessons made it possible to continue without losing time on travel. Individual lesson time was used around our child's actual needs. We were able to follow the mock results regularly. Thank you sincerely to everyone involved.

After each test, we looked beyond the score and reviewed the type of each mistake. I finally understood what was going wrong in IB Visual Arts. After a while, the questions started to feel much more familiar. The preparation felt calmer than I expected.

Using the mark scheme to review my own answer was surprisingly helpful. Thanks to TestPrep for helping me stay on track.
Wenjing Yang
- IB Diploma
I was taking IB Psychology at school, but getting used to the exam questions took time. I was really happy with the lessons.
Karina Madsen
- IB Diploma
As the exam got closer, I wasn't sure what I should actually review. The feedback I received on IB Visual Arts was clear and practical. The plan changed with my mock and homework results, so the work never felt random. Splitting time between research, making and editing kept the work manageable. My mock results gradually became more consistent. Thanks to everyone who supported me.

What annoyed me most was losing easy points because I rushed. I stopped doing a huge amount one week and nothing the next. Having the lesson move at my pace made the process feel much easier. Reviewing my work against the criteria changed the way I edited it. I found a better balance between regular school and exam preparation. I was really happy with the lessons.
Bruno Cardenas
- IB Diploma
What annoyed me most was losing easy points because I rushed. Over time, IB Chemistry became one of the most organized parts of my IB Diploma preparation. 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. Knowing what to study reduced a lot of the stress. It was an intense period, but it was worth it.
Kennedy Townsend

Our child wasn't sure how to organize the preparation for IB Diploma. The lessons started being followed without constant reminders from us.
Tomas Solis
- IB Diploma
I learned not to spend the same amount of time on every line of a long text. Thanks to TestPrep for helping me stay on track.
Catarina Barros
- IB Diploma
Breaking IB World History into smaller pieces worked much better for me. I stopped listing facts in essays and started building an actual argument. I found a better balance between regular school and exam preparation.
