Well, if you're going to a California community college (I think that's the sort of courses this program is aimed at), you would pay $36/unit. A full time student would take 12 units for a total cost of $432.[1] Things like textbooks are extra but obviously vary a ton depending on the courses you choose and how clever you are buying them.

Assuming you're not actually going to be doing a full 12 units--a reasonable assumption here, I think--the $2000 limit should suffice.

I don't know about more specific vocational schools or anything like that.
