I just started to learn calculus a few days ago and I'm not sure I really understand what I'm learning.. I can barely solve/prove anything alone.. is it normal? How long does it take to fully understand it? Does anyone have any tips for me? Things I should go over multiple times and pay attention to? Any good exercises for someone who doesn't really understand it yet?
EDIT
I just found out that in the US what I'm learning is called real analysis and not calculus
