Ah BIOS1101 or what new Science Uni students will call - BABS1101, consists of a lovely 3 hour lab where you run around frantically trying to copy things from posters on the wall.
Anyway, it's best if you keep the responsibility and wear the lab coat as well as hard-covered shoes (Trust me, don't try walking in with sneakers, I've seen a girl in my lab who accidentally dropped some dye onto her sneakers (and as sneakers have holes) it just leaks in.....)
Also, alot of people somehow tend to get on fire in first year...so a lab coat is amust!
