I know, but the University wanted acronyms in the truest sense, i.e., as was pointed out earlier on this thread, words that could be properly pronounced. That required a vowel. Eventually they gave up and just shortened the words, so it became COGS, and the school of biological sciences became BIOLS.
Another course that was offered absolutely did have to include the 'A' from the 'and': Computer Literacy And Information Technology....
