I have been an active trader for 2 years, yet when faced with the prospect of applying to grad school I get weak at the knees, I just never feel that my knowledge of how the market works is adequate. 
I hold a degree in Electrical engineering, and although I have become increasingly interested in trading systems, my trading approach is discretionary.
My question is, how do I get my hands dirty in all that lovely math, before I commit myself to an MFE? Where exactly do I start, and what is the most practical approach?
Thanks in advance.
