For me, I would do personalized report/notes regarding about
that chapter on a particular subject. Usually my notes would cover
the essential that is needed in my syllabus plus a few notable
point/info.
Figures and Tables are use very often in my notes to illustrate
a point or concept.
Though the info sources that I gotten are from internet, I
paraphrase them before typing down (to ensure I know what I am
typing, learning, and absorbing).
