How are the summer courses @ Harvard/ Oxford/ Cambridge?

Answer 1

If what you are thinking is that you can go to harvard or OxCam and take more or less the same courses that Harvard undergraduates take, that won't happen. They do have extension courses at Harvard that you can take, but it is not "Harvard College" the famous part that everyone want to get into.

There are many independent organizations that run summer courses for profit in the towns of Oxford and Cambridge, and they may use the facilities at the universities, but they are not the University of Cambridge or Oxford. Still, you get to see what the place looks like, and if you tell your friends, they wont know the difference! :)
