Elsa's teachers are wrong. Donnac is absolutely right, teachers should be teaching their students to think, and to extrapolate. Elsa was incredibly smart, even by our school's standards. I think she probably scores well on tests, and doesn't cause problems in the classroom, and is therefore sliding through the cracks because of all the other crap teachers have to deal with. It is why her peers find her to be such an easy 'victim'. As for the concentration issues, she has probably surpassed whatever her teachers are focusing on, so she is bored, and educating herself on the things she is interested in.
