At UF we start to compound prescpritions in our 3rd year. We learn everything about compounding (sterile and non sterile). However, we only compound non-sterile in lab (because labs don't often have HEPA filters hoods on) Basically, its a mixture of capsules, oral liquids, topicals & suppositories. It was quite fun for us, everyone in lab seem to enjoy it. But to answer your question, its probably closest to a basic chemistry lab. (with writeups, calculations, and so forth). Good luck!
