Hello, everyone. I have recently been plagued by the knowledge that I have no useful mathematical skills for problem solving. I'm currently in my first year of university and doing quite well with everything. The problem is, when I try working through some math problems (such as those on project euler and mathschallenge), I am incapable of adequately solving even the simplest (1 star) problems myself. I have a full highschool education- in fact, I graduated having done both years of advanced placement mathematics, pre-calc, and physics with honors (90%+ average). I still 'know' the formulae and methods that were 'taught' to me, but I find that, when it actually comes to putting them to use to solve even these recreational problems, I just don't have the capacity. I would love it if you could share some resources, techniques, ideas, &c. for learning to really put mathematical 'knowledge' into application in the form of problem solving. Thanks in advanced.
