Looks like Harvard Extension School increased their tuition cost

Can you tell us more about those strict limits on the Poetry credits with regards to an ALB or ALM if taken for graduate credit?

"Finish Your Coursework in Under Five Years

You have five years to complete your degree requirements. The five-year timeline begins at the end of the term in which you complete any three degree applicable courses, regardless of whether or not you have been admitted to a degree program. Moreover, courses over 5 years old at the point of admission will not count toward the degree."

This is the requirement for an ALM English degree. Its roughly the same language used in other programs. You should really only take the courses for credit if you plan on applying for admission in the near future.
