depends whether it's the city or the nursery schools. For nursery schools, usually three days/week, 2 1/2 hrs each day, roughly $120-150/month, more or less, pretty reasonable. The class usually stars from 9-11:30am or 1-3:30pm. You can pick either morning or afternoon depending if you child naps or not. For co-operative nursery school, you need to parcipate in the class once/twice per month to help out, and or help fundraising for the school. For some nursery schools, you can opt out the fundraising, but you need to pay them certain amount of $$$ ranging from $150-250, I found this ridiculous! For the city, 2 hrs each day, so cost just a bit less than the nursery school, but overall, I found they're pretty good.
