AND binds tighter than OR, so your WHERE clause says:

WHERE Semester = 'FA-SP' OR
Semester = 'FA' OR
(Semester = 'SP' AND Out8 = 'N')
order by AMS_Courses.CourseCatID

You need to add parentheses:

WHERE (Semester = 'FA-SP' OR Semester = 'FA' OR Semester = 'SP')
AND Out8 = 'N'
order by AMS_Courses.CourseCatID

In this case you could also use the IN operator:

WHERE Semester IN ('FA-SP', 'FA', 'SP')
AND Out8 = 'N'
order by AMS_Courses.CourseCatID
