For a typical year's worth of tuition (full course loads - five courses - for two of three semesters - I, like most, work during the summer), I pay $2,550.
This is substantially lower than what likely any student reading this pays. However, let me list my class sizes:
This, I suspect, is also considerably better than what many students get. Which worries me, because I think the focus is too much on maintaining acceptable class sizes and less on other useful uses of funds, like research. Or attracting better professors. Etc. In the long run, I don't think small class sizes determine the success of universities that desire to be more than liberal arts colleges.
