I'm not going to reply to every post individually, but I wanna say thanks to everyone. I've gotten some insight and help from every post.
I think most of my problems come from bad body position and being so stiff, especially in the knees. (among many other things lol)
Again when I took my group lesson they only got upto the falling leaf. I never had any really knowledgeable snowboarders around to learn from. My friend who is a casual rider told me to use my back leg to help turn on toesides so I've just been doing that ever since. Hopefully I can try getting on the right path when I go up again tomorrow!
Also to clear things up I never said I was carving, I meant I need help learning how to carve properly.
