Ah, good point. Seems like when annotating is given as advice on SDN it is in the context of reading a separate dedicated review source for a subject (i.e., BRS phys or MMRS) and annotating FA with bits of extra information. No way I could annotate FA with my class notes... the pile of notes from first year classes is about 18" thick. Which makes me wonder... will I ever bother looking at a single page in that stack again? When will I just give in and throw them all away?
