Agreed. Further, as a law student in the US, it is quite common for people to keep up with the reading, and then study for a day or so for many of the exams.

Agreed. Further, as a law student in the US, it is quite common for people to keep up with the reading, and then study for a day or so for many of the exams. Granted there are harder exams (and harder teachers) that demand more, but it is fairly trivial in some classes to get an A without too much studying. I would however, be very surprised to find a student who had done no prep, studying for an hour and getting an A. In the law especially, there are some basic ideas, but in many cases, you must have an extremely nuanced understanding to correctly analyze some problems (see, for instance, problems relating to conflicts of laws) and even then might end up missing something. I think this guy is british or a citizen of some british colony, so they may do things differently, but all in all, I think we are not getting the whole story here. That being said, I do like some of these techniques, and I imagine that if one were to become good at them, they could save time. Would the overhead be worth for most folks? I'm not sure, and I would say, likely not due to dropouts, giver-uppers, and those that already had decent self-developed ways to absorb material.
