In Over My Head

I think I might be in over my head. I have a 3o minute voice lesson once a week and a master class once a month. (3 lessons and masterclass) Well, I have decided to compete in NATS (National Association of Teachers of Singing- or something like that) its a voice competition. Last year I competed in the Adult Belter division and this year I am doing it again. But I have decided I want to compete Legit as well (legit is somewhere between classical and belt). The thing is....I don't sing legit. I have done one legit song in my life. NATS is the first weekend in march so that means I have exactly 4 lessons to learn 4 songs. Two of which are TOTALLY out of my comfort zone. Great. Here is what I'm singing: (click on the titles to hear the songs)

Legit:
Vanilla Ice Cream from She loves me
Love don't turn away from 110 in the shade or Your Daddy's Son from Ragtime (I have yet to decide on one- feel free to leave your vote)

Belt:
Here I am from Dirty Rotten Scoundrels
Woman from the Pirate Queen (I was going to do a solo version of You are My Home from the Scarlett pimpernel but I now realize I don't have time to learn and perfect it so I'm picking something I already know)

I know exactly 1 of these songs well, another 2 semi well and the others not really at all. like I said 4 weeks to perfect 4 songs....in WAY over my head.
