Honestly, I absolutely hate it when I take personal-notes on a subject (take the Punic Wars for example) that is required for a class, and yet when we take an exam on said subject matter, the notes I take are completely worthless seeing as the examination never asks any of the information I put on through my notes. ;A;
And it sucks when a teacher basically says "you should have taken the notes I wanted/thought like me," or something along those lines. I mean honestly, how does that work?: People have varying degrees of what they believe is important to the subject at hand, and how am I supposed to know what you want?
