The short answer is probably.
I attended UCF for a year and half and took my Unix class there. Most people didn't know what Linux was, about 50% of those who did know what it was thought it was an old OS from the early 80's and the other half were people like us.
The long answer is yes you'll have a leg up in the class. Most students won't know anything about Unix let alone what a shell does. It seems like most Unix and Systems Programming courses deal with teaching studenst what Unix is, what the basic terms are and how to write shell scripts.
