How big is the US and world education market in US$?

I’d like to know a few things. Education in terms of 1. higher education undergraduates and postgraduates admission 2. Educational books, textbooks, and other material market 3. Peripheral products, eg notebook computers, electronic dictionaries, etc 4. Educational services – private tuition, career guidance, etc. Or could you please point me to a report I can read on the internet? Thanks

upper level classes cost about 200 dollars a credit hour. Books are about 100 to 150 a piece, a laptop will run you 1000, private tuition in 6 to ten bucks an hour but most colleges have learning labs where if you assemble a group of six students for tutor session the college will provide a free tutor, and here is the site you requested:

Hope this helps.
