Yeah, when was the last time you wrote code on a whiteboard when you WEREN'T in an interview? Definitely good advice, but I would caution that it's just an interview skill, and only serves to improve your performance rather than your content.

Also, you should remember from your test-taking skills that time asleep is more valuable than time studying. Thus, as pointed out, you should really make sure you're well-rested.
