Ok, thanks! That's a good message!
Oh and I have made my decision! I'll try out for basketball! I have decided like this because I know I would't be happy in my exchange anymore if I do no try out! I know it's a great risk and I have to take all the reponsibility if smt would happen which i do not hope! So cross the fingers for me guys and thanks for for support and help altough I am doing something really stupid now!
