I prefer to take classes on campus for two reasons. First, students can get feedback immediately if they have questions in class. For example, I was confused by some basic concepts of ecosystem at the begining of a biology class, so I asked professor for more illustration, then he explained to me with more understandable language. In comparison, my confusion will remain for a while if I'm studying through the Internet, therefore the rest of the class won't going well. Second, studying in school will be easier to concentrate than studying online. To be specific, students are prone to click other websites or play computer games when they find no teachers around. But none of these will happen while studying on campus.
