How can I prepare for my school musical?

Question:

How can I prepare for my school musical?

I'm trying out for High School Musical. Not because I want to be an actor, but because it's one of my favorite Disney movies and I think it'd be a great experience!

But there are some problems. I can hardly sing. How on earth can I improve my voice by March?? Any suggestions?

My role is Taylor. (The African-American girl). Stop this video at 1:04 and 2:55 to see her. http://youtube.com/watch?v=k7zzbb17fvo... She has few lines and never sings solo. Perfect for me.

Singing is my only worry. (I'm not THAT bad at acting and dancing).
Someone please give me tips. I have until early march (March 5th) to get my singing down.

Please and thank you.

I DIDN'T get the part. I haven't tried out yet. When i said "my role IS taylor' i meant "i want to be taylor".
