I need help with my Irish dancing!?!?

When I first started dancing, I was the best in the class. My teacher loved me, and I was such a good dancer. But that was like 5 years ago, and now I'm not doing as well as I would like.. I'm not the best in the class.. I try to work on my steps at home, but some of them are so hard for me! I HATE and can't do my slip jig or hornpipe at ALL. I am going to another 2 and 1/2 hour, much more intense dance class on the weekends, but things just aren't enough. What else can I do? Do you have any drills or anything I can work on at home for like up on your toes, turn out, etc? Thanks sooo much - I'd really appreciate it.
