As said above, do you actually have the CCNA or just the Cisco Academy semesters? The actual CCNA exam you will have to pay for, but usually your final exam in the academy will give you a discount for this if your score above X%.
The basic stuff you do in college is unlikely to help you get much, as you say you didn't pay much attention and the answers are online anyway.
I did the CCNA and has since expired, I've had a job where they considered renewing it but weren't really bothered I had it. I was a sysadmin and we were required to configure switches and firewalls so not a network engineer etc. If you were working in a data centre which favoured Cisco kit then a CCNA is nice as it gets you to a CCNP quicker for the employer. Realistically the CCNA is pretty basic and in my experience doesn't help a great deal.
Having said that, it's not a bad thing to have and does last three years and can be renewed by progression. I did however interview someone who claimed to have a CCNP, I suspect they had only done the class exams which are really just prep for the main exam(s), a few simple questions and it was fairly obvious they had never done the real exam.
