Nanodegrees are small 6-12 month courses that build up your portfolio and get you ready to work at a job full time.
At the moment, it's mostly computer science (if not all) classes, but the courses are created by accredited sources like an online tech institute, Google, and such. They're sponsored by different tech companies as well.
Would this be an alternative to a four year college? It's only 200 dollars a month and, compared to a college, that's 10-20x less than what you'd pay for top grade education.
The other claims are of getting a job with a minimum payment of 70k a year and up to the low-mid six figures.
Opinions?
Having half a knowledge of something can be very dangerous. Point here is whether the students taking short-term courses will be that competent and educated as the regular degree holders?
They have prerequisites to follow before they can actually take the course so that is the other half of the knowledge learned. I cannot guess on this nor have I taken any courses (yet, I'm curious to see what's involved) so I wouldn't know how competent they would be despite even reading testimonials.
