More Info about MIT Math Prize for Girls?

Hi I got a 114 on the AMC 10A and a 123 on the AMC 10B this year… what are my chances of getting into the MIT Math Prize for Girls competition? I literally just learned about this competition today, and they said that they take the top 300 girl applicants… 123 is barely above the cutoff score so I’m not sure about my chances.

In addition, if you’ve attended this contest before, could you tell me a little bit about what it was like in general?
