Disagree, somewhat. With assignments and stuff, sure, I thrive when i have a deadline to work to. Give me weeks and I'll procrastinate badly.
Stressing about exams though is a sure fire way to fail, for me. My advice if you're getting stressed about an exam from studying it is to take a break. You may work efficiently (for assignments and things) but it's not a good environment to really be understanding and having stuff sink in.
