If you tell me what you are looking for, I can tell you if CalArts is a good fit for you or not. Generally the people who get in are either super talented, have an amazing personality (driven to do work, to experience new things, etc) or both. Very few people with almost no experience, and those are usually the “naturally gifted” ones.
If you can prepare your audition focusing only on CalArts, I would prepare a Shakespeare piece that fits your age/gender and a contemporary piece that is super different/uncommon, preferably that is also very physical.
