I find practising a lot always helped me out. When you really know the material you are presenting, I think that helps with your confidence. Also, if you find yourself getting a little flustered, keep a water bottle with you and just stop and take a sip of water. Gives you a chance to gain a little composure.
As for classes, I am not in Calgary so I can't really help you there.
