Question

how to see the video in lower resolution? slow internet connection :(

Answer 1

I doubt it's possible. Instead you can download all the videos and watch them independent of connection speed.

Answer 2

Yes, it is quite easy to download the videos via iTunesU for viewing offline.

Answer 3

thx for your attention :) I found another way. try to view it in lower resolution, via youtube :) .
NB: how I envy MIT students..! they got very good education..
but thanks to ocw.mit ;)
