I'm gonna be real, if I had kids them gettin' bad grades would make me mad AF
Schools not that hard and for me, parents (western parents) have far too low a standard when it comes to education. All this "we're all different" that's rubbish, the tests are designed to be passable and you spend 5 years learnin' the exact shit that's gonna be on the them
I'm not sayin' everyone has to be an A student that's silly, but if you on a D you should be able to bump that up to a C with hard work and then the challenge would be stayin' there.
