I had PJ for MCDB 101B. Avoid at all costs. Lectures were unclear and he was unable to help clarify with explanations, seemed unfamiliar with the class material. Tests frequently had mistakes on them and were mostly free response. Everyone worked up until the bell for both midterms and majority of class took the full three hours for the final.

Took PJ for 101B. He is the worst professor I've had at UCSB. He is terrible at explaining simple concepts. His exams test on the tiniest details he barely covers. He goes off topic regularly. You get half credit on clickers for getting them wrong + there were almost no clicker questions. It's 4% of your grade. Also giant mistakes in every exam.

I took Joshi for MCDB 101B. I would not recommend taking him to anyone. His lectures were horribly unclear and confusing. He was not very accommodating. His exams were difficult and unfair. Questions on them were confusing and were based on things he briefly mentioned in class. Worst professor and course I have had at UCSB.

I took his MCDB 101B. Do yourself a favor and don't take his class. He does not know how to teach. His lectures are very confusing and he makes a lot of mistakes even in his exams. He expects you to memorize every detail and write 4 or 5 long short answer questions in only 50 minutes plus 4 or 5 genetic problems. Just terrible.
