“Learn at home at your own pace, with the ability to go back to steps & concepts you do not fully grasp.” That’s the key for some of us. As a child, I was out of the classroom for half the year because of contracting a few childhood diseases sequentially. I did the homework assignments and received a prize for getting the highest average in the class. As an adult, a career change necessitated more math classes. I did them via correspondence courses from the state university and reported for exams that were purportedly the same as the ones given to their onsite students. Straight A’s. Would not have been able to do that in a classroom situation that rushes through the curriculum and doesn’t allow one to digest and play with the concepts.
MIT & other colleges now have many of their lectures available free online. When I make the time to do so, I enjoy sitting through those lectures.
