I never, ever, ever listen to other peoples' recommendations of "how much" studying to do.
For one, one person may take nearly twice as long to read a given amount of material as someone else just in terms of sheer reading speed.
For another, one person may have a wildly different approach to "passes" through the material (eg read through things 4 times to get retention vs reading once and annotating)
For another, the pacing and scope of material does vary significantly from school to school.
For yet another, people's' studying varies differently in terms of efficiency. One mans hour may actually include two coffee breaks, checking ESPN, and playing a quick game of Bejeweled blitz on their phons, whereas another may actually have a dedicated and focused hour.
Finally, I simply don't trust other peoples' quantification of their studying. It's a combination of recall bias and gunning. There's a reason this thread is already becoming the "do you even lift, brah?" of studying
