Database Schemas

I am needed to create a database schema for the following situation:

I need to store a program (degree) and then I need to store it's requirements. The problem I am having is that some requirements can be filled by multiple classes. For example an English major can take either "College Writing 1" or "Basic Writing 1". I need to somehow store these paired together that either of them can be taken to fulfill the requirement table. Please submit a schema diagram that can complete this issue.
