you don't need to take it. also, i'm pretty sure that it doesn't have a concurrent 51C requirement, so if you do decide to switch to pharm or smthn later on, you can take just the lab. i suggest don't waste your time: its not gonna do much to improve ur GPA (its 2 units only) but you dont want a big fat C on your transcript if you happen to not do as well.
I agree with other SDNers. Do not waste your time with a lab class. Lab classes are a lot of work. Instead invest your time with other classes to increase your GPA (if it is not 4.0 ).
