Where is that? I graduated in Philippines in one of the known universities. If I were you research the schools/universities and check was is there passing rate last local boards. Also check the faculties and their experiences. With this at hand you will be able to decide which one is the best for you.
There are instances where in SENIOR LPN's are making more than a newly graduate RN. Sometimes the salary is based on experience. My question to you is, did your employer told your hourly rate when you were hired? If yes, then you should get the salary as agreed upon.
