Mentioning senior year extra curricular in application

If you play sports (let’s say soccer) and you were on the soccer team from freshmen to junior year and plan on playing senior year do you say you did 4 years of soccer or 3? Applications are due in November which is before soccer season even starts.

Not a problem to indicate:

Soccer (9-12). Colleges know that there are winter and spring seasons. You’re fine.

Agree, you should include it as long as it is your current plan to play during the upcoming season.
