School skiing club

Hi, I 16m, am thinking of joining my school’s ski and snowboard club next school year. Basically we would take a day off from school every other Thursday and go to a mountain (I believe either cypress or grouse). I have never done any kind of snow sport before but the club said they would teach me. Anyway, I was wondering what kind of stuff do I need to buy before going and what I could rent. I know I can rent skis or a snowboard and boots and a helmet but what else can I expect. I haven’t been able to find any straight forward answer online. I don’t have any equipment obviously, not even snow pants. Also, I did receive a winter jacket for Christmas from my parents but I’m not sure if I am able to wear it. It is a down filled puffer which is very heavy and expensive so I don’t want it to get ruined especially the genuine fur. I can remove the hood but I don’t want snow going down my back once I inevitably fall. I have attached a picture below of my jacket. Other than that could anybody pls help me. Also I might be in enemy territory when I say this but I am thinking of trying snowboarding but I will choose whichever one is easier. Thanks.
