3) I would do away with grades and results, and the all-encompassing belief that your ability to perform well in school says ANYTHING about you as a person. At least in the system where I live your status among teachers and peers is almost solely defined by your results. It puts bad students off learning because they are repeatedly shown they are "stupid", and it puts good students off learning because they get to deal with a lot of jealousy, and it's easier to be mediocre.
If kids are expected to enjoy learning, imo they need to study in small groups of people wit similar skill levels and interests.
I know plenty people who at my age still believe good grades make you a better person and make you happy. It's just what 12+ years in our educational system teach you.

1) I don't think I would cast that spell. I'm more scared of knowing what people think of me than not knowing. And more importantly, I am a very private person irl, and I wouldn't want everyone to be able to find out whatever they wanted, without some control on my part.
