As far as a waiver goes I am unsure about getting it at the board. I think you are required to have it before applying to the board. It all depends on what you got in trouble for as well. I was a nervous wreck because I thought I would be required to have one, I got a ticket for drinking underage my freshman year in college. It was deferred and not on my record anywhere but my recruiter told me to report it. He said it does not even require a waiver and wont really affect me unless there is someone with the exact qualifications as I and that could be a deciding factor other than that dont worry. I hope it doesnt become a factor but I would say to still pursue a waiver.
