I highly recommend that you watch tutorials and practice in your down time. Sites like Skillshare, Linda.com, or even YouTube offer a vast amount of tutorials. These can help you get started in any programs you might need to learn for your classes and can give you a leg up on your classmates. If you've already got the creative side down, learning the technology will be your first step. See if you can find out what programs your favorite animators use and start using them! Most programs, such as Adobe Creative Cloud, offer student pricing for subscriptions. Try to get started with these programs as soon as possible so that by the time you graduate you are creating amazing work without stumbling through the technology!
