What are some of your good and bad study habits?

My good and bad study habits are that, I always wait last minute to review and study for the test.  I sometimes get distratic from like Facebook and Twitter.  Some of my good habits would be that before my tests I go to my teachers and ask them questions about somethings before I go study. I also go to my papi for homework if I needed help. Thats my good and bad habits.
