This is exactly what I'm doing, going to nursing school then applying to PA program. You will need to take Chem 2, O Chem I, and an extra writing course. Like many others have already stated, requirements vary depending on the type of program you're applying to. I know for a fact, that you DO NOT need to have any clinical experience. The requirements for the schools in Texas are, having a BS, completion of pre reqs which are very similar to the ones for nursing school, and passing the GRE. PA programs are very competitive but it is such a great profession. Good luck to you!!
