scared for recruitment

I got accepted into cu today and already committed!! I’ve always wanted to be in a sorority, but from what my older brother (who’s in a frat at boulder) was telling me over thanksgiving break, it seems like getting a bid from a good sorority is going to be nearly impossible next year as 300-400 more girls rush each year. Since this year about 1500 girls rushed, that means almost 2000 will be rushing next year if the trend continues. I have average grades, an average appearance, and an average amount of money. I’m just scared I won’t stand out and in turn, won’t get a bid. Any recruitment advice?
