comment How can I learn to “read maths” at a University level?
I think you might want to try a tutor. I mean, it doesn't have to be one that you have to pay. Why can't you ask one of your classmates to help you out? The mountain to climb might turn into a tiny hill.

comment Understanding change of variable in measure spaces
Thank you! I was actually going to write it for simple functions as an answer in response to your comment. Regarding your comment: what does extend by continuity mean? Isn't it enough that simple functions are dense?

@ShaunAult: thanks! I'm not sure I understand why I cannot treat $1$ as a basis though... Could you tell me more please?
