From my experience (both as a student, and working in higher education), I know that for me - lectures are for the most part a waste of time. Now, this isn't for all classes - but a number of my classes would have been far less burdensome if I had been allowed to simply study the material on my own and then complete assignments/tests as needed; appropriating lecture time for Q & A rather than covering all the material in the text.
I am sure that many NT students might feel the same way - but for myself, it wasn't so much that I had to sit in class and "waste" my time - it was that my time spent in lecture consumed a great deal of energy just to maintain composure in that environment.
But more than anything, is that I find most educational programs are too rigid, and provide very little in actual application. I have to be given the freedom to go down rabbit holes without the constant pressure to complete a meaningless task.
For me, formal education is a hurdle to overcome, not an opportunity.
