Proven false, there's a whole documentary about this I recommend you watch called 'How High' that studies the effects of cannabis on university programs.
I honestly didn't know you could prove a joke to be false or not?


(not to mention there's no such thing as proof in science, but I presume you've summarised in your own words there and aren't being literal?)
Not to mention that 'proof' would have to be statistical not absolute! Some people fuck up
badly on weed in the wrong circumstances, in fact a few even may go temporarily psychotic under it's influence, some become negatively habituated or demotivated to even continue an academic course.
It's hardly worth an argument over a joke, but it's
not absolute that weed will make everyone's exam scores better or at least no worse and personally I disagree with suggesting to others it's definitely fine to get stoned off ya tit's at uni/college/school!
I don't believe anyone's ever shown it to be a definite learning boost vs. not taking cannabis at all? And anything else isn't absolute for all people.
(I'm not including the rare cases where cannabis provides a definite medical relief from some symptoms such as severe pain, epilepsy, etc. that could effect learning and exams)
A documentary can be correct or incorrect - have you found some new research that shows weed has no negative effect on intellectual performance (or exam results which aren't quite the same thing)?
That would be genuinely interesting if you had any links, or the documentary provided proper references? I would be interested to read those if there are any you could pass on?
Last time I preordered I spent the month waiting pouring over the manual. Then I joined this site and read 200 pages of Tempest chatter.
What am I supposed to do now?
This time you've got your 'pest Mk.1 to keep you company and help pass the time!
