I have made a big mistake by signing up to an advanced functional analysis class, when I do not have the background. This is my first analysis course ever, and aside from that my math background is very light (one semester calculus, two semesters stats, one semester game theory). Alas, the die has been cast and now I am trying to keep my head above water and survive(pass) the course. I have a midterm in about 20 days from the date of this publication. I would like some opinion on how I could muster a semi-decent-not-really grasp of what is going on to get half the marks(just enough to pass). We have basically gone through Metric, Banach, and Hilbert spaces(their topological properties and key theorems to analyse them) and some applications. I have been told that the exam will be to apply the properties of these to economic problems (I am an economics major). Any advice on how I could approach my studying to be efficient would be greatly appreciated. Thank you!
