LPN to RN has advantages and disadvantages.
If you can go straight to RN, I think that is always best, but putting your life on hold while you wait for a spot in an RN program that may not even happen for a year or two is NOT the best use of your time.
Going the LPN to RN route will give you a sound background when you go back to get your RN, but you may develop bad habits and find RN school more difficult or you may try to answer questions based on how it works in the "real world" where as nursing school
is all about the "text book" way of doing things. This may cause you to answer questions incorrectly and lead to a difficult time passing unless you learn to "rethink" your way of thinking.
The great thing about nursing is you can "customize" your career. Some people do LPN-RN-MSN-FNP, some do LPN-RN, some do ADN-BSN, some go straingt to BSN or MSN. The choice is YOURS!! Good luck with whichever route you decide to go. Do not forget to enjoy every moment. As far as working and nursing school, some people can some people can not. It all depends on what type of student YOU are. Some people spend 8 hours a day and fail nursing school and others study 4 hours a week and make all A's.
