Peter,
I really appreciate all the help. Unfortunately, the query you came up
with still returns two rows for catalog_number = 520.
I modified your query slightly to this to qualify a specific catalog_number:
SELECT c.course_id,s.course_offer_number,s.subject
FROM course c
JOIN
Tina
Basically, if the subject is ME, then I want to select that row.
If there is no row for that catalog_number that has a subject of ME,
then I want to grab the row that has a course_offer_number of '1'
and a subject that is not equal to ME.
Is this what you mean?
SELECT ...
FROM
Peter,
That was the first query I tried, but for some reason, it still pulled
all of the rows. So I've been trying to come up with another solution.
Any other ideas?
Thanks for the reply.

Are there multiple rows which meet your WHERE condition? If so, and if
you want just one of them, your need another WHERE condition.
