Comment University is about options (Score 1) 347
University degrees about giving yourself options, and learning structured problem solving. Most, but not all, of the good to great programmers that I have seen have all had university degrees, but not necessarily Comp Sci, Comp Eng, or Comp informics. One of the best programmers has a philosophy degree. The university degrees are about giving you broad perspective, and not just about giving you the skillz.
Having an university degree is not essential, but it is way easier to get ahead faster. The vast majority of people I know who do not have degrees tend to be very naive about their view of the world and problem solving. Learning calculus may not give you direct programming skills, but it will give you another lens in which to view the problems that you need to solve, as just about any subject that has any rigor. The old adage of "you only get out of something what you put into it" definitely applies. If you are cruising through uni on all the fluff courses, your not doing yourself any favours.
It sounds like you want to get out into industry, but consider your financial implications if you do. Personal circumstances vary hugely, so if you are not giving up a free or heavily subsidized education by parents or scholarships, then my advice is get out to industry, and see what's what, as quick as possible. If you're currently on student loan it will not cost you anything to wait a few years, and you'll probably value the university education more. Who know, you might that you actually want to that Zoology degree.
