the next year than you know, cramming everything right over, over one long weekend or something. Actually in education we actually know that spaced repetition works better than cramming so the same same thing, same body of learning. If you learn a bit every week and space it out you actually have much better long-term retention than if you try to cram everything in short-term so there's, there's a very solid result that we know from pedagogy and how the human brain works. So, so if you're able to- so so again the way I, my life is my backpack.
