Most schools have a deadline of April 15th right? And I know some are April 1st... are some as far back as May 1st?Also if you have an April 15th deadline, when should you send in your payment, like 5 days before at least? Are they strict with the cutoff rule? How does this work? I think for example, the April 15th deadline would be the date they need to HAVE your deposit, not mail-by date, correct?
