this entire thing reads like a fantasy. or some reddit thread where "everyone clapped" to me.
if I was told by a professor on the first day of class which I paid for that I wasn't allowed to use my own note taking method I had been using for decades, I'd just say "No." and if pressed further, I'd take it as high as I needed to. or get a full refund for the class and find another.
this isn't an elementary school. these aren't children. these are adults.
