Alot of your classes from your BS will count,you will have to find a nursing program,you could get an associates in 2-3 years at a cpmmunity college. The hours for the case managers are awesome at the hospital that I work at,they work M-F,8A-4:30P,and take like one weekend call a month,much better than us floor nurses,atgghhh,I complain,but being a Pediatric nurse is the only job I could imagine,love those kiddos
Good luck,and I will help you in anyway I can.
Oh,the coarse work...normally 1-2 lectures a week,and 1-2 clinicals a week,alot of colleges offer evening/weekend options now.
