I heard law school prep courses are a waste of time. They teach you the same stuff you learn the first week in school.
It is smart to target BTL's as I know we do feel under-confident starting the year...
Of course it's worthless. But if it makes people more confident than they'd be otherwise, then it's valuable.
(I suppose the confidence would be from knowing they aren't missing out on any valuable prep, because there is no valuable prep...)
I did some sort of pre-law course they offered me free. It was as worthless as an unactivated vr, but at least I didn't feel like I was at a disadvantage going in compared to the people who did one.
