you mean how many times over to read them?, I think twice is enough, but do end of chapter EOC questions at end of each. Plus write down notes from each reading for finals days quick review, Formulas, key definitions, key examples. And writing notes helps hammer in the concepts and becomes easier to recall
do 2 readings - and start to do the tests earlier. While doing the tests “re-read” the portions of the curriculum that you feel yourself needing more info.
Just reading the text 2, 3 or 4 times without any practice is not a very useful way to spend your time.
To add to this question, I just finished reading all Schweser books for the first time. It took about 6 weeks and I made ~150 very detailed notecards. I was going to just start practicing like crazy now; any thoughts?
