I'd be a little careful with your one-line dismissals of fields. Each field has hundreds of people dedicating their entire lives into it. It'd be offensive to them that someone who hasn't even done any research to think they can judge an entire field like that. Imagine a high school student who took a community college course and saying "University juniors don't know anything. I discovered that they just copy from Wikipedia." The advice in this thread is a great starting point.
Actually that is his genuine opinion which reflects his interest. I also happen to point to you that I would also be more careful to judge community college courses. There are people doing great things over there too - dedicating their entire life.
