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.
Jason, College, United States
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.
Abigael, High School, Switzerland
Like that time when I was already 2 hours doing my homework and nothing was working for me to understand what was going on.
Sarah, High School, Brazil
Like last week, I was completely lost on implicit differentiation during class, but I went back to my dorm and used UpStudy, scanned my problems, did their practice problems, and it finally clicked. The best part is I can get the most detailed explanation and guidance!!
Jason, College, United States
My "aha!" Clicked in when UpStudy helped me with my Physics Homework even though I'm in newbie and I just got UpStudy I still think that I will use it or at least the next 20 years 🫣😂📚
Abigael, High School, Switzerland
When I was so lost in my math homework, I was trying already 2 hours to be focused but I wasn't getting it at all! And so I tried the app, I wasn't expecting to understand everything at once, but with the AI tutor's help I did it!!
Sarah, High School, Brazil
I'm pretty sure there are a bunch of other freshmen in my class using UpStudy too. It's honestly kind of amazing that such a helpful app. Makes me feel a lot more confident about taking Calc II next semester.
Jason, College, United States
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. But ever since I got UpStudy, I only have to learn 1 hour a day for any test or pop quizzes, and boom! I score well on every test! You should definitely try it out!
Abigael, High School, Switzerland
UpStudy is such a great app, especially If you are a self-taught person the AI tutor can do so much for you and your apprenticeship.
