I hate studying the day before tests. :c I always feel like I know enough to justify stopping then and there, and goof off instead. ...Which is a terrible way to prep for a test.
I know that feel. However, it has happened to me lately because I've been VERY lazy. I don't know what the heck is wrong with me. I did pretty damn well in high school, but as soon as I entered college, I became the king of procrastination. :c Good luck!
