Do colleges like if you do music intensives?

*repost--I posted this in the wrong category*

So, I've been singing for forever but taking classical lessons for just about a year. I've been told that I'm progressing nicely, but the lessons alone don't cover everything I should know. So, consequently, I've started doing intensives this year to amass more knowledge. I'm already doing one based on music theory for the singer, and I'll be attending a week-long intensive in August. Hopefully, I'll find more during the school year.

I've been wondering if this makes one look more attractive to prospective colleges. I'm a rising junior in high school and would like to double major in college---one of the majors having to do with classical voice. So, does this help my chances or is it nothing special?
