What to know for field hockey? never played before?

I'm going to do field hockey this freshmen year of high school and I'm super excited! I've never played field hockey before and I have played soccer, but just for gym and leisure. I wanted to know what I should do to prepare for tryouts so I can make the team. The coach said that usually everyone makes the team but I want to be prepared and ready. What are some basic skills, moves, etc that I should work on? How should I practice? thanks!
