I know you didnt ask for tips but back handsprings are scary to learn but when you are learning what always comforted me is to always keep your arms straight. As long as they are straight and not collapsing you will be ok. The bhs may look bad but at least you made it.
I like Gold but am ready to move on to Platinum! So I never competed Silver actually. A person who has never competed can join bronze, silver or gold without any previous experience. No I am not 19 I am younger but not by much so I am very old for this level but Im having fun so that's what matters!
