Called CASPN a few minutes ago and set up an appointment to take the admissions test! They only offer it twice a month... one of which is a Thursday... and I'm never off on Thursdays, which limits me to the Saturday test. I'm taking it April 17th. Test Prep Review has a big study guide/practice test for the TEAS test, so I'll be doing that in the meantime.
From what I'm told, you find out within a couple of weeks of taking the test whether you get in or not. By the beginning of May, I could know whether or not I got into nursing school!
I hate waiting so long to take the test, but the gal on the phone recommended having my app in by the end of May. One of the nurses at work said she applied, took the entrance exam, and started the program a month later, so it's not as late as it seems.
