ccas?

hello! i’m currently waiting for my JAE posting results and i need some advice regarding whether i should join a sports cca that i’ve been interested in (training 2-3 days per week if im not wrong, can last till 9pm according to reddit; school is near my house so location shouldn’t be an issue) or a club where i can ‘relax’ in. i’m not sure if cca will drain my energy to study after school, because i do find it fun, but at the same time i’m not sure if i’m willing to ‘sacrifice’ my energy and time on it instead of studying for a levels, any advice would be appreciated!
