How do you memorize pharmacology for the NCLEX when you're tired and have little time to do it? Instead of one drug at a time, start learning four or more drugs at the same you learn side-effects and nursing considerations.
After many, many years (20!) of "thinking about it", I finally decided at age 45 to go back to school for nursing. My mom was a nurse for 50 years and even though I have two other bachelor's degrees, the timing was never right for the commitment of nursing school.
