A&O Science 2: Air Pollution

<p>Has anyone taken this (with Stutz)? I'd love some insight on the final, he told us the midterm would be conceptual, but it turned out to be more fact-based than I expected so now I am at a bit of a loss regarding how to study. Help would be appreciated.
Also, how was the grading scale in that class? What percentage was a B, a B+, an A-. etc?</p>
