mindlessly doing questions won’t increase your score if you dont know why the answer becomes that, i dont know your current score for rw but i like to rewatch all the basic videos for english just as a refresher so i nail down the basics, also taking notes doesnt mean they have to be pretty, its the fact youre writing it down that matters because then youll remember it more easily, so even if no one can understand what you’re writing just do it, and you dont have to write everything down just the basic rules etc but yea id recommend revising and making sure you actually know all the basic rules for english first
