I am in my 2nd year associate degree RN program, my grades were in the low 70's and I was afraid that I would not be able to bring them up to passing and would end up failing. But, you see, I already failed one semester in the 1st year(my husband had a heart attack and open heart surg, I missed 2 wks of school). We cannot get back into the program if we fail twice, so that's why I made the decision to drop, so I can go back when the new semester starts in January. I felt awful, like a failure, but there are quite a few in my class that are failing. We have 2 new instructors this semester and they are doing a fine job, but a lot of the students are blaming them for using the old teacher's tests. I really don't know what my problem was, but the day I talked with my advisor about my situation and she said that I made the right decision and all, it seemed like a weight was lifted from my shoulders. I love school, though. I am 46 years old and I think sometimes that it is harder for me because of the age thing.
Oh, well, don't feel so bad, you can always go back and finish when it's right for you. Good luck in all you do.
