What have been the drawbacks of taking online classes in USA?

It does take up a lot of your time, for the most part. It's always going; it's a year-round thing. You do get a month off here and a month of there, but as far as planning vacations, you have to plan your vacations around your school or expect to still be doing school work because you can't make things up. You have to stay on task because it is so accelerated you can't really just leave it and then come back. There are a lot of components that you have to do on a daily basis. So being able to step away can be a drawback.
