My study notes -- like virtually everything I have written for the last 30 years -- are solely in grey pencil [0].
> Use coloured pens
That didn't work for me, for two reasons:
Firstly, with coloured pens or highlighters, switching pens slows down the process of writing too much. Instead I just use pencil, and summarise, focusing on making strong logical connections with other stuff I am learning.
Secondly, I don't read my notes enough that colour makes any difference. I found I retain information best by writing, re-writing and summarising. Actively writing engages all my brain. Just reading notes isn't enough to make it stick.
