You are in the same position that I am. I am 45 years old and completed my LPN last August. I did amazingly well in the program and I am currently completing the course work toward my RN. I don't think you are too old or you are wasting your time. I also did this to set an example for my teenage son who didn't believe educations was important. Please don't ever doubt yourself--and continue regardless of what other people say. You will be thankful you did it in the end.
This sounds just like me. I decided to put the books away today and come here to hopefully figure out what I am doing wrong. I think I am trying to do too much at a time and it is making my brain turn to mush. I finished in August and did well all the way through the PN program. I am going to pick one study guide and stick with that. Good luck to you.
I've had the same problem. My suggestion is if you have a Pearson Exam Cram, use that information since the test is administered by Pearson Vue. I have nothing to base that on, just the most logical thing I came up with.
