School For The "Old Dog"

They say, "You can't teach an old dog new tricks," but I am about to break the mold on that one. In less than 3 weeks I will be returning to the world of a college student. YIKES!!! I won't lie, I am very petrified, not just scared, but petrified. It has been 11 years since I graduated college and so much has changed since then. This class in an online class, which I have never done. It does have its up side:
I can go to class anytime during the day
I don't have to be dressed up, I can go to class in my P.J.'s

The down side is:
No professor to talk to, have to send an email and it will take 24 hours to get a response back
The grade is based on responding to the chat room and 4 different papers
I haven't had an stimulating "English" based conversation in 6 years
I haven't written in about 11 years.

I think that my biggest fear is not being able to articulate my words the right way. For the past 6 years, my conversations have been with my children 5 1/2 and 2 1/2. I can tell you anything you want to know about Bakugans, Beyblades, He-man, Star Wars, Cars, Disney Princesses and Strawberry Shortcake, but to talk about literary terms and use them correctly, let's just say I am worried. I bought the book for the course about 3 weeks ago and have been reading in it every other night, highlighting and labeling all the important information, (at least I think it is important).
The main reason for me going back to school is to renew my teaching license so that I can work again. I need 6 credits, two classes, to accomplish this. I feel very out of my element. Hopefully, as the class progresses so will my cognitive thinking process.
