While I’m rather relatively new at this myself, I find that picking one DAW and learning it inside and out is a good place to start. If your school doesn’t have specific classes in such things, you could possible take some online classes from Berklee. I took a handful of classes on Orchestration for Film and TV a couple of years ago through their program and it worked out rather well for me. Other than that, there are several books on the market to teach yourself how to use a specific DAW. If you’re the kind of person who is good at self learning, this may work for you.
