I agree that although there is less competition for boys, it still will be tough competition.
But somebody has to get those spots in the program, so why not you? Since you are only a sophomore now, you have lots of time to get ready for the competition you will be facing. Do whatever you can now to improve your MT skills--acting, singing, and dancing. Take all the acting, singing, and dancing classes you can, get in as many shows as you can, etc.
The spots are going to go to people who worked really hard, so make sure you are one of the people who worked hard!
