When I took it, I found it challenging but was really interested in the course so it made studying for the exams a little bit easier. I ended up with a B+. Just a tip get ready to know lots of pathways for Immuno.
Is it a pre-req for most dental schools? I don't think it is. Does it look really good if you can get an A or B+? Probably. If you are interested in taking it, do it-don't just take it for dental school.
