Hayes is straightforward about what info he is going to test on. Grade is 20% m1, 20% m2 and 60% final. He lets you drop 1 midterm if it benefits your grade. For 131L- switch to a new TA if you have Kaitlin S. She was outwardly rude to students and made the class environment very uncomfortable. Worst TA i have had at UCSB

This was so far the easiest MCDB lab I have taken. The exams were all online. Also the experiments were very low stakes, not like O Chem labs where if you really messed up you would miss a bunch of points.

The entire class is based on a 33/66 structure with 2 midterms and a final. The 2nd midterm is where it gets everyone, the curve is to a C not a B or B-; you have been warned; which means many students got a C in the class, avoid this class if you can or wait for a different instructor other than Dr. Hayes.

Professor Hayes is a unique guy. He's nice, understanding, and very knowledgeable, but sometimes he's blunt. A lot of material isn't found in the notes, so definitely show up to lecture. Provides study guides and practice tests. Grade is made up of exams only, textbook was a good supplement but not necessary. Exams seemed very fair to me.

Lectures are not recorded and final grade is based off 2 midterms (20% each) and final exam (60%). Or one midterm can be dropped and the final can count for 70% of your final grade. The first exam was easy, but the second two had low averages. I would avoid this class and prof. if possible.

At the beginning of this class he told us a story about how a kid hucked a loogie on the sidewalk, how nasty that was, and how he told the kid off. After taking this class...I wanna huck a loogie right next to his feet. Material is really really dry, very condescending, fact dumps, and is just really boring.131L is cool and helps the lecture.
