I heard that cramming the day before finals is supposedly bad for you. But I guess some people's studying methods are like that and they can't change since they are used to it already. Whatever works best for them I guess. Drink energy drinks, like Red Bull. JUST 1 DONT DRINK MORE THAN ONE OR YOU WILL DIE. I'm in engineering too and I can see next that next week I'll be doing the same, yikes =/
