Technology/science courses usually have a shorter "shelf life" than do courses in subjects where the subject matter does not become obsolete in several years. The three named schools may have different policies that should be spelled out on their websites or in their catalogs..
It truly depends on the content of the course. There are courses where the content has changed significantly in even the past five years. Computer stuff comes to mind here. Other areas haven't changed in nearly forever -- take the life and times of W.A. Mozart for example. I have general academic courses on record at Excelsior that are well over 10 years old.
Locate the course description from the appropriate year Good Morning, I would contact your old school and locate a copy of the course description of the course in question. I hope this helps. Hille
