2 ?s: Just how difficult of an area of study would you say Computer Science is, & job avail (more inside)?

There are various areas of CS, just as in say Nursing. What little you know about computers will be of little help in advanced CS. How are your math skills and do you like calc? You will be spending a lot of time in higher mathematics and computations. Computers and computer science are both progressing geometrically, there will always be work for the qualified individual. I would perhaps look for an accredited program I could take from a semi-local university mostly online.
