200% more caffeine than you'd find from your local coffee shop.
I agree with this person "I can honestly attest that group projects don't work. A group of 4-5 usually had 2 "leaders" that would direct the work, write the most important parts, and fix the bad writing and bad ideas from the others. Thus, bad kids never got better, but still made decent grades. If the English majors can write 15+ page papers regularly on their own, so can business school kids."
Group projects teach self-reliance, and that's about it.
