I'd highly advised against. If you're bored with your present study or don't like it, persue something else (speak to the Counsellor -- and yes, there are course counsellors who can advise directions to persue). In this job market, anything that can get you an edge is worth it. Today, at least in Canada, you need -- at minimum -- a degree or diploma to even be considered for a position beyond flipping burgers. The market is tight right now and staying a bit longer in school may not be such a bad thing..

Ultimately the choice is yours however... We can give our opinions but unless your heart is there so you can devote your study time to what you need to learn, then it won't make a difference if you stay or go.

Out of curiosity, why are you asking? Are you feeling disillusioned with study (what are you studying anyways)? Is it a cost issue?
