Hello Guys,
I have recently purchased Self Study materials for a SANS Course. I wish to know how do you guys go about it?
Do you guys hear Audio First or Read their books first or do both of them simultaneously??
Since i have observed that once we hear audio we don't concentrate so much on the written words in books other than slides.
And if i just start to read books without hearing audio sometimes i doze off (I know my bad 

 but it does happen even if i have utmost interest) However i wake up after that power nap and again start.
Still i just wanted to know from you guys which method do you guys follow for those of you who follow the Self Study route?? 

I even thought of reading book, hearing audio and then making index all at once but it would take a really long time to complete a single unit and i wanna do it fast too.
Hence it would be really helpful if you guys share your experiences too
