On the web there are many good sites for learning to put it mildly.
But did you know you can take college courses online for free? For some of these you can listen online to prerecorded lectures/discussions. http://www.ocwconsortium.org/ has a listing of courses online. MIT has courses there as well on http://ocw.mit.edu/index.htm . Another good site is http://www.apple.com/education/itunes-u/whats-on.html. The latter has mainly courses on audio. Among other colleges having open courseware are Tufts, Notre Dame and Yale a pretty good selection to say the least. Just do a google search for "opencourseware". Best of all they are free! A lot also have downloadable handouts as well. You also can search on youtube.com for lectures and courses. Type the name of the college or university followed by lectures or courses and see the selection available.
A good way to continue your lifelong learning with no admissions application, tuition, fees or other costs.
