Would it look bad if I were only to do a sport in 11 and 12th grade? Would it seem like I was doing it just for college acceptance even though that isn’t the case?
Don’t start a sport just for your college resume. It won’t ever look bad to start an activity—so if the alternative to playing a sport is more time to play video games, then by all means start a sport. If starting a sport in 11th grade means you drop doing something else you enjoy, then think twice about it.
Do you love it?
Well I did do my first sport my Senior Year. It won’t look bad, you can just write an essay for your college applications on you changing/ facing a challenge during high school
If you like the sport, go for it. If you want to get in shape or make friends, go for it. If you are doing exclusively for college apps, don’t bother.
