Unfortunately, limited or inaccessible professors are common with online learning. With you have to rely on e-mail or a phone call to get into contact with them to ask a question and some people are dreadful replying. For example, I enrolled in an economics class and asked a question from the professor and never heard back, but
whenever I had a query about the course the professor was never available to answer it. Another flaw of online learning is the social aspect of college, is that it lacks the true college experience, i.e. the parties, futurities and clubs.
In online learning may not be for everybody, but it is a fantastic choice for those who simply want to learn and avoid the social aspect of college, or those that have careers and families that need attention. Online colleges allow them to get a degree in their spare time went out without having to drive or take time off work or family life to do so.
