I would suggest talking to your band teacher and read articles about the reality of finding full-time work in the industry today. There isn't a lot of work these days. The more things get computerized the less people needed. Don't listen to the recording schools they paint a great picture to get you to sign up, but then find out maybe one or two of each graduating class finds work and will be in debt for year paying back school loans. I'm not saying don't do it, just know what you are getting yourself into.
The good thing about the modern recording world you can put together home system and start learning the basics. Start recording friends and get a taste for recording. If doing good maybe find some artists you don't know and find out the what its like to deal with artists. In recording besides being a good engineer you need to have a lot of people skills. Get a bit of a local reputation will help in finding some intern work in a studio. In fact ask your band director if you can hand out with him at a recording gig offer to help setup and break down. See what the real world is about.
Last start listening to ALL types of music live and recorded and get a feel for the sound and mix. As engineer you don't pick who you work with so you need to be able to deliver any type of music. All there are a lot of recording websites start reading the postings and articles they will give you a feel for a gig in recording.
