Notes as you go or read to get through the material? everything, extensive, material, through, reading

SWASH

I am almost done with the first Schwester book and just finished Sampling and Estimation. This is the first reading I did not take extensive notes on. I sort of just read everything through once and tried to take it in without taking notes, and then did the concept checkers at the end immediately after. I was able to get through the reading much faster this way, obviously. I have heard from some people not to stress on the reading much, just to get through it so you have more time at the end for problems and tests to review.

Anyways my question is are people taking extensive notes as they go or are they just reading to try and get through the bulk of the information. I just am starting to think it may be a waste of time especially with the Schweser Secret Sauce book which is basically a completely condensed version of all the notes books.

Thanks.
