Replying to College

I think college is the biggest waste of time and money when you can learn anything you want on the internet. There's exceptions of course, for things that are better to learn in person. but 90% of the things people learn in college, you can learn on the internet. like why would you pay 10,000 dollars for a math class, when you can learn math for free on the internet? it's pretty dumb lol
what do you guys think? did you go to college? do you think it's good or dumb to go to colleg?
