In Ruby, while "and" exists, it's not quite a synonym for "&&" --- so, in comparisons like this, you should use "&&"

Looks great, nice submission... Also, I can tell the non-US developers by how they approach the junior? method. If you're in the US, it's grade == 11, and pretty much everywhere else it's something different. (amusing to me) :)

It was even different within Hungary some time ago, when I was in a foundation high school, they added extra grades. (In mine there were two optional extra grades.) Of course, since then, the education system has changed a lot to be more uniform compared to other countries. :)
