If it's woody at the bottom or you can see a distinct difference between top and bottom it could be last year's. Here they don't do much more that germinate and make a couple of leaves in the first year but it's hard going so yours might do better.
I think 3-5 feet a year is a typing error An oak won't be 60-100 feet tall on 20 years. They're slow growers, that's why the wood is so dense.
