> Probably will start with either linear algebra or maybe set theory? This can work. I spent a year or so before grad school at work, I brushed up by spending a summer drilling through a Linear Algebra book. A new thing I have been trying out recently is find an application, find something I am confused by, dig deeper through the layers of mathematics till I uncover the basics of the confusion, then re-learn and work up. So BFS vs DFS. The latter seems more like up my alley. YMMV
