I'm in the same boat. I am applying to a school where they hardly take people in. Around 3000-5000 people apply and only 300 get in. I am thankfully good with my studies (except Calculus...urgh!) and I want to get in. Let me know what your method is.
I think what matters is what makes you feel best. I think if you follow that, you should be set. But I'd love to hear your opinions on this.
