Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, and now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with an A+ while I'm bad at statistics. I took on extra classes this year because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart, I have passed all my exams! No more re-sits! At first, I was happy with a pass, and now I only get good grades. Many thanks!

I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on each stage, my speed, and the pleasure I have in learning.
For the first time, I finally feel confident about the way I learn. I have the perfect overview and have made significant progress in terms of speed and the grades I get. Thanks, Chris!

The most considerable effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school. Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any Ds. My average score is now an A, and those are results I would have never had in the past.
With my old method, I passed only 3 out of 8 courses. However, since I started taking my notes digitally in Study Smart, I have passed all my lessons on the first try. For me, StudySmart takes away the stress of wondering if I will give or not.
Thanks to StudySmart, I passed all my exams and with better grades than before! On top of that, I have mastered a perfect study method now, which I am confident will help me earn my degree.
