I applied to 18 law schools, with most law schools acknowledging receipt of my application between December 8th and 16th. Most of those law schools fall within the top 20. So far, I have only heard back from 1 school (an acceptance), and that was the single school that I had applied to in January. It's been total silence from the other 17 schools -- no interview requests, rejections, or acceptances. Is this normal? Should I be concerned?
