Campus students do this also, taking their exams outside of classroom at the testing center. As you can see, the Internet class takes the same amount of time as the campus class. Some services have very strict word limits on the size of email messages, not allowing a whole assignment to be sent at one time by a student. In past semesters, I've had students who have had to divide up an assignment and send it as Part 1, Part 2, and so forth. Try to find out before the semester begins.
Some companies regularly purge emails stored by clients from their system.
This means messages you might have been saving which relate to the course are lost. Check if your provider purges emails before the semester begins. Both Hotmail and Yahoo will allow students to have free email accounts. For either program, you would log on as a new user, setting up your email account. This is important to do no matter who your provider is, since it is always possible to experience a system crash.
