I really envy the educational content which is so freely available these days and wish it was there during my college days.
Youtube has plenty of well presented videos, making it fun to watch.
Sites like Coursera, EDX, Udacity provide micro/nano degrees on plenty of university subjects.
Sites like Udemy, Lynda provide tutorials on softwares like Photoshop, After Effects and other lesser subjects for whom you wouldn’t want to pay a fortune.
On top of it, they launched MOOC (massive open online courses). They are really extensive courses which are equivalent to what you would study in University.
Are you enrolled in any?
