Red pen, slashy slashy

Ijust had to post this. It's from one of my students exams, I asked a question regarding infection, immunity and vaccinations in particular. This is what I got:

Passive Immunity-antibodies stimulates from everywhere.
two types of vaccination: 1) booster 2) zooster

Mind you, this in no what whatsoever answers the question, except for part of the question asked them to "name the two types of vaccination we discussed in class".

Someone shoot me. *sigh*

why do I bother to go over this in class? why do I bother to make powerpoint notes? why do I bother to send them to the students and suggest they buy a book? They obviously are not using any of it.

Back to my grading.

Red pen slashy slashy.
