I'm a slow learner when it comes to this?

Alrighty, so I'm on my school's dance team and practice just started today. Now, we aren't even going to have our first game until after Thanksgiving break (which is next week). So, during practice, I noticed that I don't get the dance moves as fast like other people. I know I can dance, but I want to learn the dance at a faster rate so I can know what I'm doing when our first basketball game comes around. Now, I know, I know, it's only the first day, but still, people are learning it faster than I am and I want to be able to learn it faster. Plus, I want to have more confidence when I dance so that I'm positively sure that I'm doing it right. I kind of get self-conscious when I show my talents in front of others so this dance team is helping me break out of my shell. Anyways, can you please just give me some tips on how to learn the dance moves faster and have more confidence in myself when dancing? Thanks! =)
