Critical - I can't even begin to remember what it was like to be an overwhelmed college student, but your crazy schedule sounds a lot like what I'm hearing from my son. He's pretty bogged down with papers due, finals, auditions and rehearsals. This last week he was in a musical and was doing Algebra backstage during intermission. Just hang in there girl, and make sure you get as much sleep as you can so you don't get sick. That would be the last thing you need right now.
