Ex: Forgetting to normalize the unit vector.  3 Wrong equation Ex: Forgetting to square the magnitude components under the root sign.  5 Returning a vector answer for a dot product calculation.

Don't take off more than what the problem is worth! Make sure they end up with at least 5 points for trying on an exam and 2 points for trying on a homework problem. (If they did try . . .)
