text: Students not learn to much taking online class because they need to receive a good explication about the class, as real a teacher explains in the school. For example, if you are a student but you have questions and doubts, but the classes online or videos conferencing does not answer and give you good explications about the class. Would you learn while you are keeping in mind all your questions and doubts? Other reason is that students do not learn taking online classes from home because they get confusion, not understand the class and they give up when nobody help them.
