Congrats Sharppi!!
I joined a beginner school in MN as a true beginner two winters ago and it's honestly probably the best decision I've ever made. Now I'm playing ~twice a week and it's the best part of my week, every week, hands down.
You'd do well to get some real ice-time in between now and then--I did public skates maybe once a week the summer before I started. Skating is hands-down the biggest determiner of success, and it's also something you don't have a chance to really focus on during games.
And don't fret too much! At low levels (at least in MN and CA) I've found people are very level-headed. They get that everyone's there to learn the game and have a good time. You'll be absolutely shocked how far you've come after a season or two.
