College is now more expensive than ever. We know so because we're writing our student debt into our will and hoping our grandkids don't have to write it into theirs. This goes doubly if you're thinking about getting into a STEM field like computer science. Thankfully, computer science is also the only STEM field that consistently pays well and doesn't require lab time to learn (suck it, physics!). Learn the real deal and open doors to a variety of careers with a mixture of high- and low-level programming languages, databases, algorithms, data structures, and software architecture. Black leather trench coat is optional. Get this complete CS education for $39.
If you want to cut right to the chase and learn the most in-demand tech skills, then allow us to point you to web development. Getting armed with full-stack knowledge of web tech will prepare you to make everything from mobile-responsive e-commerce apps to the next Facebook if you so choose. Will they one day have a gripping drama made about you starring Jesse Eisenberg? It's hard to say (though we'd suggest that you demand Samuel L. Jackson). But at the very least, these skills will allow you to build you own site from scratch and be your own boss. Pick up this web development course for $14.
Those little rounded rectangles (graphic design nerds call them "squircles," because they collect face punches as a hobby) on your iPhone screen aren't gonna make themselves. Well actually, Apple's XCode development environment does do like 95 percent of the work, but you still have to learn some magic computer words in the Swift programming language. You'll build projects like a Pokemon Go app, Snapchat clone, and a soundboard for some Y2K-era prank phone calls so you'll have a portfolio to score yourself a freelance gig. Grab this iOS 10 app development bundle for $35.
