In-class doodles

Why do my notes always end up like this?

Why do my notes always end up like this?

So it’s finally the end of the semester. Classes that seemed to last forever were coming to a close.
But not before cramming for finals.

I like to think of myself as a pretty good student. I go to class most of the time, I study, and I read the books.
But the other day, I sat down and spread all of my notes around me, ready to use the semester of note taking I did to my full advantage.
I started going through my notes and realized something that was of little help for my exams; all of my notes either were covered in elaborate doodles,
or the notes were doodles themselves.

It turns out I spend most of my class time doodling rather than taking notes, although I did write down what was important.
I have a theory that keeping my brain active by doodling helps me though, it keeps me from dozing off or zoning out in class!
