Top Law Schools

Hello!

I was waitlisted last year at a couple T6 schools, even received a status call from one, held until each respective school's orientation was over, and finally denied. I decided to take another year off and apply a lot earlier than I did the previous year. My question is how can I show my commitment to attending one of these schools? Addendum? Do I bring up the waitlist? Previous reapplicants, any strategies?

Thanks!
