Here are the rules:
Closed book, closed notes, no web access, closed everything (except your minds). Tables of physical and astronomical constants are included in the exam. You can use a pocket calculator, but not if it has display of formulas and such. You cannot discuss the problems with anyone until after everyone turns in their exams.
You have a maximum of 4 hours (but it should not take more than 3) from the moment you start until the moment you finish.

Good luck!
