I bring up law school, medical school, dental school, etc because if your advice about b-school is not based upon experience, then you might as well comment on the others since you've not attended those either.
As for law school, once a person gets through the first year, they're good to go. It's still not easy, but the learning curve is hit the first year and once you figure out HOW to learn the law, then learning it is very easy.

Unfortunately I have yet to attend B-school so of course this is coming with a grain of salt. However I did attend an M7 undergrad and took several core business classes at the business school, and also have many classmates in the b-school with whom I've discussed their experiences.
I don't know you are bringing up law school, which in my opinion is a lot more academically rigorous. Not only is the grading more strict but the level of knowledge and preparation for exams is on an entirely different level. Just the idea of making hundred-page outlines would be enough to scare many business school candidates away.
