The UG online masters of computer science is a good option. Many people in this site speak highly of the curriculum[1]. Last time I checked the total for the entire curricula if you pass every course on the first try is around $7000. As a bachelor holder myself looking to break into some of these higher-salary and in-depth roles I’m certainly considering it. It’s even better if you have a company that will pay for it, and because it’s so cheap even the most meager offerings from companies will cover a good portion of it.
