This class was an absolute joke. Don't get fooled by his grading system, the homework seemed easy, but no partial credit (averages ~ 50/100). Studying for the exams were a nightmare because there's so much material, and he never emphasized anything. The exams were insanely difficult, NO amount of studying could have prepared me for them. avoid!

The exams were so hard and non related to the lecture materials. Slides contain minimal amount of word explanation. Teaching us like graduate students. Always write random things on board which make the whole class note so messy and disorganized. The worst professor at ucsb and avoid this person for your own good. Recommend MCDB 108 series!

He's a very smart professor and it shows during lectures. I really liked the content of this class. But the exams were grueling- He teaches so many topics but only covers a select few on the exams, making it hard to prep for. The TA was very nice tho. I would really recommend taking MCDB 108/110 since those classes are more clear and fair.

His grading policy may seem fair according to the syllabus but then each homework assignment and his exams are graded on what seems like a completely arbitrary rubric. We never even found out what our final exam scores were and then they posted our grades after the due date for GOLD. doesn't really seem like he cares that much about students

He made his class incredibly difficult. Homework assignments were vague and unclear and his exams were taken home and open note but he designed them to be extremely difficult so it doesn't really matter what resources you use. His slides don't really contain much info so you really have to write down what he says.

The material is interesting, but the class is unnecessarily difficult due to poor structure. Exam topics are briefly covered in lectures, making it hard to study. Grading policies are unclear early on and very harsh, with little to no partial credit. There may be a curve at the end but overall the course feels stressful and disorganized.
