(I am 12 yrs. old; I take 7th grade pre-algebra)
Cornell note-taking is VERY hard, unless you are a person with
MANY questions, and have the ability to not copy off someone on the
Internet. (I did that a few minutes ago)
Best of luck!
P.S. At my school, we have asked nearly every one of our
teachers if they had heard of Cornell Notes........they didn't.
