If you take it at a UC, make sure you take it at one of the top 5: (LA, Berkeley, SD, Irvine, Davis)...or better yet at just LA or Cal for the name recognition. Might as well milk it for what it is worth.
It's just you'll pay up the nose as a visiting student, which was approx. $203/quarter unit. That's about $812 per 4-unit class. Compare that to $20/unit at a CC.
Mix it up and take a few classes at UC? Better yet, get on track to transfer using a TAG agreement to a UC, that way, if you don't get into pharmacy school...you'll be on track to earn a B.S....and you can reapply once you get it (or sooner).
