That's not true, I have a really bad felony and I got accepted to a very good nursing school. It was hard and it took a lot of effort but I got in. What I did was first volunteered at a hospital for a while and received A's and B's for the pre classes they required. The volunteering helps a lot.
It would do you good to have your record expunged first because schools and colleges won't accept you if you have a felony and they can find out once they do a background check on you.....the best to you
