Usually I read more normally, or just look up things that I'm interested in, but I have a different style when I want to "force-read" something unfamiliar. For each chapter:

1. Read chapter subtitles subsubtitles, etc, and the summary if there is one at the beginning or end.

2. Go thru the chapter reading the first sentence of each subsection

3. Again, reading the first sentece of each paragraph

4. Again, reading everything

And for bookmarking and hilighting I have 4 categories: important, interesting, unanswered question, reference.

And if I have goals for reading, I write them on the back few pages and fill in information as I find it.

I usually do this on paper, I still find it kind of awkward to do in the Preview app or whatever, and it is not possible for me on a phone.
