I read on TLS that it is best to send two. I think it was a harvard law school admissions officer (or the head of harvard law school admissions) who said that.
I asked this question to an admissions officer at Loyola Law School, she told me to wait until the score in available. They told me that they would not look at the application until the LSAT score came in. I am going to wait.
@dreamville , same situation. I caught them before they could forget me a long time ago. I asked an admissions officer during a visit to St Johns, and she said I could still use it.
