teachers

I am working bringing and old drupal site up to date and replacing the current course database from something made in Visual Basic to something in Drupal.

I have created a content type with a bunch of CCK and taxonomy to categorise the course but I am having some troubles and I am hoping I can get some feedback on best practices to creating an online course database. Some of the problems I am having:

1. The same class can be offered by distance, intensive (1 week long) or standard semester. Do I create three different nodes, one for each time the class is offered?
