Re: applying to nursing school
Be real and honest in your essay and interview. Don't tell them what you think they want to hear - people can see through that. Answer their questions whith your mind and heart. Show them who you really are as a person (provided "who you are" is a reasonable person).
Be able to explain why you want to be nurse and not a scientist or physician.
Competive programs (ie not the lotery or wait list ones) usually give a few "points" for being a men, much the same way they give points for being and under represented minority. Male URMs are sitting pretty I guess. I went to a very selective program and a faculty member told me this.
Good luck! Becoming a nurse was one of the better decisions I have made.
