LPN a waste of time? I don't think so. I was a LPN for 10 years before I returned to school and became a RN. I think that was the best option for me in persuing a career in nursing. Opinions will vary on this subject - there are several threads from the past you could read that offer various perspectives.
As far as no one responding to your thread ... you may want to consider not referring to LPN education as "a waste of time". I understand this was stated TO you and not BY you - however, I found it a little offensive. My LPN cap from graduation sits in a glass curio right beside my RN graduation cap, and I am very proud of both of them.
I also have several friends that are practicing LPNs that have no desire to become RNs and there is nothing wrong with that either. If you are interested in finding out what the difference would be for you as far as practicing, contact the State Board for Nursing in your state and they could answer any questions you have because those will vary from state to state.
Good luck! I wish you the best in nursing school in which ever program you decide to enroll. Keep us posted!
