I disagree, the PCAT is very important. It is a tool used to define your competency and knowledge on the appropriate subject matter. Many schools value this test, and it can be a major determinant on your application.
The PCAT can be your saving grace if you have a mediocre GPA. And yes, schools do accept the January PCAT if their deadline is after the day of the PCAT.
I know that you're going to ask, but the PCAT is only 1 week away from the deadline, just set the PCAT settings on PharmCAS and submit it. Those deadlines, are deadlines for you to E-Submit, not deadlines for the schools to receive the information.
Once PharmCAS has all your information, they will send it to the school. So, your information will probably be received by schools at the end of February/Early March.
