Happy New Year.
I just graduated from the BMCC evening/weekend program and I worked full time the entire three years I attended nursing school. I will be honest in that it is a lot of work and will require a lot of your time for labs, lectures, and study time, but do not let anyone discourage you if it is what you want. Classes usually run twice a week from 5:45pm to 9:15pm with labs on the off days and clinicals on Saturdays from 8am - 4pm or so.
Some people found it easier to leave their jobs while studying, especially in the last semester because it is difficult and the material very dense, however, for those who could not (like myself) leave their jobs, you had to look deep within yourself and really make sacrifices to get through. I am married with no kids, but as you may or may not know, being married is a commitment in itself and requires time. Nursing school puts a lot of strain on life, be it work or your personal life and especially your free time (what free time?!), but if you have a strong support system, you will make it.
I can provide more specific details on the program, expectations, etc. If you are interested, send me a PM and we can correspond that way. I truly enjoyed the program and learned a lot. Despite what you may have heard, the staff is great and very capable. You have to utilize the resources they provide in order to get out of it as much as you can.
Best of luck in your studies,
