#1. You are average of 5 peers you hang out with (a good thumb rule).
#2. There is a huge valley between Software Engineering vs Computer Science (what is your goal here.)
For #1. meet-ups and getting programmer mentor is good idea.
If you really want to do pure CS, there is no alternative to college, but for Software Gig, a good programmer mentor gives better direction than College/University.
edit: this advice is primarily for second/third tier universities or comparing with them.
