What subject are you on now then?
Btw...I found out what learner I am just from those notebooks
For ages I have been doing revision cards with just lines of words and no pictures to revise, and I got fairly average results
With the notebook, everything that I used diagrams for stayed in my memory.
E.g, I couldn't remember much about the carbon cycle because I just wrote words
I can remember almost everything about Darwin's theory of evolution via natural selection, just because i drew a picture of Darwin xD
So again thanks alot, using your tactic helped me to find out what I should do. I think from now on I'm gonna do visual methods. Good luck man!
