Calculus-Pro

I downloaded this app expecting to learn calculus but it didn't teach me it just gave me questions that I didn’t understand. I was going to give this a 2 star review ⭐️⭐️ but i reconsidered I figured out that this app is probably for people that already know what calculus is so maybe you could have an developers note or something like that. This app will be very helpful when I learn calculus, so keep up the good work!
