From a cost standpoint, almost always. Be wary of one is quarter system and the other semester as credits might not transfer as expected.

back to the original question. A degree will help and generally will put you in a better spot (especially for your fist job or two) but is not required. Make some websites, build a couple of tools, start a small portfolio. Then start interviewing to get interview experience. Learn more from the types of questions you are asked. If you have a place you would like to work, don't interview there first; get some practice beforehand.
