"Virtual Office Hours" refer to times that I spend on Internet answering
student's email. Unlike ordinary office hours, these are flexible and mainly
depend on the number and complexity of questions that I need to answer. Since
the very nature of an Internet class is "asynchronous", you should not expect
an immediate answer to your question (particularly if you are asking for
help with a mal-functioning program!). Nevertheless, to speed up our communication,
I will, at the beginning of the semester post approximate times when I am
likely be on-line. Check the announcement part of your schedule page
from time to time, as these times may change.
