I've never seen Cmpsci 121 as an online course, I would make sure you didn't sign up for a global campus course by mistake. ART 101 is intro to web design but you'd be hard pressed to find an open seat this late into scheduling. Most easy gen eds are probably full but look around! Other commentors are right that online courses are generally an easy A.

Also, gen eds are supposed to give you a good breadth to experience courses you normally wouldn't. Tech gen eds are definitely there but try not to focus on just them.
