I agree with Jeanette73, there is no class that you don't need. The more education you have, the broader your world view will be, and the more you will see how all things work in sysems, with rules, and applications to health care (not to mention the rest of life). I myself had a degree in chemistry when I went to nursing school, and that was immensely helpful. But also all of the other science and liberal arts courses were useful, too. One of the most useful courses I ever took were my 4 years of high-school Latin--all of those strange abbreviations like stat., p.o., BID, etc. (and et cetera is even one,too) are all latin, as are most medical terms.
I agree with your plan to become an LPN first. See if you can handle the academic work, then graduate, get a job, and go back to school at your convenience. The unfortunate thaing is that your job prospects as an LPN will be somewhat limited. Have you thought of what specialty you would like to be in nursing?
