calling all networking experts

I was wondering if all the networking experts could help me out. I am studying CCNA in my spare time. I run my own business during the day. I do not have a clue about networks and have thrown myself into the deep end. I have come across this sub-netting stuff. I read all the material and finally think I have it cracked.
