1. Analysis (10) -- Including both Real Analysis and Complex Analysis, the one I've been thinking of taking but never had the chance.
2. Graph Theory (20) -- A discipline that has absorbed concepts from many different fields, more like Topology.
3. Metric and Topological Spaces (10) -- A introductory Topology course, seems to be quite easy so far.
4. Analytic Number Theory (20) -- Very hard, I believe. It deals with problems like WHY a series convergent or divergent, or WHY there are infinitely many primes...It's quite interesting, but like Graph Theory, it's Level 3 course, my advisor recommends me not to take this one, but I just don't feel like taking Mathematical Biology, so I chose it. -_-|
