@Cobrat-- Can you cite some facts to go with your assertions?
On #2-- looking at the websites of at least 2 of the programs, there is no difference in degree requirement for full/part-time enrollees.
On #1- limited to my personal experience I wouldn’t call these pre-professional. The folks I’ve known entered the workforce for a number of years and then decided that the challenge of the program was something they wanted to do.
