i tend to agree with argonaut on the length of time needed to study specific topics, sure one can learn some aspects of number theory, combinatorics etc under a few hours however to actually understand the basics and then the more advanced requires much more work, ie, constant thinking about relevant concepts every single day. I'm not necessarily talking about UMEP here but rather mathematics at a higher level in general, one does not need to do exercises and practice questions over and over, in fact i haven't done any maths exercises since year 12, however thinking about problems and going off on tangents when you think about a problem is crucial for higher understanding
however doing better than someone in VCE maths means jack shit lol I did better than kamil in vce maths, does that mean i am in a higher position than kamil? no fkn way, kamil rapes me anyday
