I love Trello! I use it for everything really, but it was especially helpful for LSAT studying and law school applications. I feel that I only use it in a basic way though, if anyone has favorite features I would love to hear how you use it.
For me I started with powerscore. They are really good for the basic stuff and can give you a beginning to start with. Then I would read the lsat trainer. Hands down some of the best strategies are in the book.
