I've never heard of CLEP, but it sounds pretty cool. Regarding Berkeley, I would definitely call the admissions office like polkadot said. Try to call during their hours, which might be different from you if you're in a different time zone. I had to call several times each day and they never responded to my emails or messages. Just keep on trying!!! But once you get ahold of them, they're pretty nice about answering all your questions.
Polkadot: Hahah...that's funny how you included co-op cop. 🙂 BTW, I nominated you for president!
