text: Another reason is that students will not be able to receive as much help in the classes that they take online. Students in online classes will have missed much of the information in the lectures, so they will need to ask someone questions about what they missed. However, there will be nowhere for them to ask these questions. One option for these students would be to email a teacher. However, a response from the teachers may not always be reliable - in the past, if my teachers respond at all, it has taken some up to 4 days to respond. The student may be in urgent need of this information for an upcoming test, and if they aren't able to get the information on time, they will not be adequately prepared for the test. This becomes ever harder in subjects like math where every unit tends to build on a previous one. If a student misses the information and isn't able to ask a teacher the question, they will start to fall behind, possibly causing them to fail the class.
