List of online courses to improve your job prospects or earn a raise. Many are free or offer need-based scholarships.
Beyond the obvious benefits (making yourself more employable, shifting career paths, etc.), taking online courses can do a lot of good in other ways. If you struggle with work ethic or motivation, taking online courses can help train better habits and build confidence. If you're shy about learning from a professor or with other students around, you can learn in private and without that anxiety. If you're overwhelmed with working two jobs or irregular work schedules, setting aside even a short amount of time every day to do a lesson can add reliability and habit to your life.
Personally, I find when I put even a little energy into learning something (when I might otherwise have browsed social media or played a game), it's left me feeling more motivated for the rest of my day. And the sense of accomplishment that comes from learning something actively can be powerful.
GENERAL EDUCATION SITES
EdX - Free online courses from major universities in a wide variety of topics (economics, biology, programming, business, etc.).
Khan Academy - Free online courses in a lot of topics. This was started as a way for a guy to teach his nephew through Youtube videos and turned into a whole big online education system now. It's largely focused on high school, but includes AP (advanced placement) level courses, college prep, and test prep (SAT, MCAT, GMAT, IIT JEE, NCLEX-RN).
Coursera - Financial Aid is available. Wide variety of courses often linked to universities and many offer certifications.

DATA SCIENCE / PROGRAMMING
I'm listing data science / programming courses specifically because these are good programs and because programming, data science, and similar fields are ones where employers often care less about degrees than they do about skills.
Coursera Data Scientists Toolbox - Financial Aid is available. Data science, data analysis, programming, etc.
Dataquest - Free with limits or Subscription. Learn data science, data analysis, data visualization, python, data engineering, etc. Some free lessons, subscription based access to most of the content, but no limits on how fast you go. If you are motivated, you could work through a lot of lessons quickly and make it very affordable.
Code Academy - Free with some limits, or Subscription. Learn Python, HTML, Web design, SASS, and more. Many courses are free. Projects and quizzes require a subscription. They also offer 'Intensive' programs.
If you're looking for work in a second language, or if a second language may help your job search, or you simply want a more fun way to get in the habit of learning something new, check out:
Duolingo- Free language learning with a really easy and comfortable interface, especially when used on a computer rather than a mobile device. Completing a course won't make you fluent, but will give you a working level ability.
Mango - Free (through library). Language learning is often free with your local library card.
Mondly - Free with limits or Subscription, but has many languages including some that Duo and Mango don't have and they often offer discounts on their monthly or annual fees.
