One thing that I do that actually helps with retention and speed is I use the “finger method.” As I read a passage, I follow it with my finger. There are a handful of studies that show we don’t need to see the whole word to identify what word it is. I’ve been able to gain so much time and absorb so much more information by just tracking the passage with my finger. Each time there’s a paragraph break, I stop and write down my one sentence summary.
