It's a logic exam. It's worth 50 points.
3 really easy problems are worth 7 points each
5 easy/medium problems are worth 10 points each
3 moderately difficult problems are worth 15 points each.
I will grade a maximum of 5 problems -- indicated by the students.
Extra-credit is possible.
My only real worry is that my students aren't good at math (that's why they're in this class) and they aren't good at following directions.
Also, if they don't do well on it, they'll need to take the final.... which I don't want.
