Why was the following question closed?
I ask because it is a very natural question, and one which has the potential to be useful to future users. The question asks for advice learned from experience which would be useful when starting out studying a maths degree. Sure, it is broad, but...surely this site is meant to be more than just a place to get your homework answered? We have so much experience and enthusiasm bubbling under the surface, so why can't this site give practical mathematical advice as opposed to just helping you to integrate* better?
*In the mathematical sense. Not in the social sense. Definitely not in the social sense.
