To clear up, this class is "Logic, Second Class," not phil of bio.
For those who didn't take Prof. Levy's PHILOS 31, he is a very funny professor (and a super agreeable person! He agreed to give me PTE even though he didn't know who I was, but I eventually got in without a PTE), and use slides that's useful enough for self-review. The homework is much harder than 31, so going to discussion sessions and TA's office hours would be very helpful. My TA was Ian Boon, and he really knows his stuff, perhaps better than Prof. Levy. If you aced your homework, then you don't have to worry about the exams, which are definitely easier than homework, so be sure to really understand how to do your homework and you'll get an easy A.
