User sign up would typically have two phases in a User Controller:
newprepares the information to be shown on the sign up page.createtakes the information entered on the sign up page and prepares it for insertion into the database.
So it would be Accounts.register_user(user_params) (under create) responsibility to set any “default” values. The score wouldn’t be in the user_params as the user can’t set it. But register_user would “know” what default score to set.
