Assignments if the marks actually count towards your final result. Having time to go back and check what you've done the next day is invaluable to me. I still wind up writing most of it at 4 in the morning, mind XD
I haven't handed in an assignment late yet, and I don't plan to.
I can't STAND exams where you have to write essays. All my writing juice flies out and squiggles weirdly on the page. Naturally I can write well but in exams my style just doesn't feel consistent or smooth. I look back at what I've done and think "WTF is this carp?"
Also, I procrastinate badly when it comes to revision. I got a very low B in my biology mock sans revision OH MY GOD I'M GOING TO DIE
