I took a course on formal logic on courses. I put all of the questions and exercises into anki, a spaced repitition program. This ensures I will always remember it and get it in my head at an intuitive level. Basically it's like flash cards that decay exponentially. The first review is in one day, the second in two days, then 4 days, and so on.
