My method has been to audit a university class, do lots of practice problems, and find a support group of people to regularly work with

If youve taken say, trig, but are rusty, dont bog down on trying to relearn upfront. If it comes up when learning something else, then relearn whats necessary. The problem with this is if you're in a scheduled class where you might get behind. The benefit is that when you go on to upper level math, its a necessary skill to relearn some things quickly
