You may wish to start at a community college and then transfer to a college/university at a later time. The community college would be less expensive (but the credits are just as worthy) and tend to have more flexible schedules as a community college tends to attract non-traditional students like moms, adults, or full-time/part-time workers.
Do a little research first and put together a long-range plan. Ultimately, what type of nursing degree/position do you want - LPN, RN, etc? Find out what is necessary to attain the level you're desiring. Then, decide what school you will attend in order to get that certification/license. If you decide to go the community college and then the traditional college/university route, find out what the pre-reqs are for the university program and then make sure you take those comparable courses at the community college (so they'll transfer). You can probably get a TON of pre-reqs out of the way at a community college, thus saving a ton of money while you're at it.
Finally, make an appointment with an admissions counselor to learn more about your options. When you make the appointment, let them know that you want to talk with someone in the nursing department (or school of allied health professions or whatever division nursing is in) so you can learn as much as possible.
Good luck to you!
