Is this a book or video series? I'd be interested if you could provide a link to the series you mention specifically.
To my knowledge, no universities actually use the Feynman Lectures as a textbook for their introductory courses. However, some students who have already taken physics read the Feynman Lectures later and (self-)report a much clearer understanding.
