<p>I honestly don’t learn from lectures. It’s a matter of learning style. I often have attention lapses, leaving me lost for the rest of the lecture (and then copying down notes that are useless because a textbook/MIT OCW has more comprehensive notes).</p>

<p>I agree - college isn’t really useful for anything other than research, for people with certain learning styles. The sad part is that an undergraduate major is a pre-requisite for graduate school (and that undergraduate major has required classes). Of course, years ago, most mathematicians and scientists were primarily self-taught, but education has now become institutionalized, bringing research along with that.</p>
