Hi /sci/

I am going back to school for a Masters in Mathematics, focusing on probability and stochastic differential equations. Problem is, it's been a few years for me. I descended into alcoholism over some life events which occurred right before graduating and finally cleaned myself up. I mostly did algebra, all the way up to algebraic geometry and galois theory, but don't want to go back for pure mathematics and I do have more applied classes under my belt -- most of my electives were just more math classes since I'm an autist. Did do some courses in probability models which included a brief intro to SDEs.

Anyway, my main question is what should I review? I mean basic stuff. I have from now until September to get back up to speed. I'm thinking definitely linear algebra, probability, differential equations, and maybe some analysis if I can fit it in. Since I did most of these courses, I won't need to review every little thing and will mostly re-read and skip over a bunch of stuff.
