Ok fair enough I find the videos and ypt stuff annoying too, but that doesn't mean that 12 hours productive study isn't possible, and doesn't mean that people who do actually study that much 'messed around all year'. I study for 10 hours every day, and have studied year round (having not studied before y12 lol but anyways), okay maybe 9 of the 10 hours is purely studying and I spend 1 hour across the 10 just staring into space but it is possible. Equally, you definitely don't need to spend this much time studying, depends what your goals are and how you actually study. I spend most of my time writing essays and doing past papers so procrastination isn't as much of an issue I guess.
