How can I improve my study?
I'm studying physics and maths in order to pass two important exams. I need to know a lot of formulas and physic constants, sometimes is frustrating because I mix the numbers and other times they simply don't want to get into my head.
I like to solve problems but there is a lot of theory and metric units for each thing.
My brain reach a point where I can't memorize anything new, I spend a lot of hours in front of the books but I feel that I'm not productive enough.

Hi guise,

I'm going to do applied maths next year,
what to expect ?!
