There are lots of reputable online courses that can provide you with the certification and/or training you need to land a real work from home job. You should check these out if you know what type of home job you want, but don't quite have the skills you need to pursue it.
World-famous Harvard University currently offers 42 of its classes for free online. Many of these classes on edX, like Introduction to Computer Science, are self-guided and ready to start anytime you’re are. Others, like AnatomyX, run on a fixed schedule. Some even offer college credit through the Harvard Extension School for a fee; otherwise, completion earns you a nifty free ‘Honor Code’ certificate.
