Tests are graded

People definitely did better on this test than the last one. Still unpleasantly many uses of the "universal distributive law", e.g. "e to the a+b equals e to the a
plus e to the b", or "(x^2 + y^2)^n = x^2n + y^2n". Algebra misteakakes are a real killer in this (and basically any other) math class.

The grade boundaries (remember these are approximate, and that the eventual grade is calculated from the number, not the letter):
00-10 F
10-20 D
20-35 C
35-50 B
50-up A
Way more As and fewer Fs this time.

I'll have the answers posted later in the evening, and sometime soon the grading scheme for each problem. The tests will be back tomorrow.
