It is one of the best study apps that I have ever known, for me it has been very easy to pass exams and workshops that the teacher gives us. Furthermore, this is not like those other apps that only give you the answer, it gives you the explanation and everything now I can understand many of the math things that I didn't understand before, for me that is highly recommended.

UpStudy has been a total lifesaver for me this semester. I was pretty nervous about Calculus I since math wasn't my strongest subject in high school, but UpStudy has basically become my go-to study buddy.

Math is my biggest weakness. The signs and the numbers are just too confusing for me, especially when there's a four-digit number or more. And I also have anxiety when I raise my hand, and I am afraid that if I say a solution that might be wrong, I'll be humiliated in front of the whole class. That's so embarrassing.

UpStudy is a great app to help you with your studies, especially if you're struggling. I used to practice hours and hours, and I still got a bad grade.
