What level should I attribute to this material?

I’ve been thinking about importing some of the lessons available at MIT’s Open Course Ware website. But I don’t know what level I should attribute to them. I was thinking about Intermediate 2, but just to be sure If any of you could give a look at the material and tell me what you think should be the level attributed I would be very grateful.

Here is the link for the video (with subtitles) of one of the lectures:

Taking the opportunity, I’d also like to suggest that some of the content of this site I mentioned was added here at lingQ, they provide transcript and a downloadable version of most the video lectures. :slight_smile:
