The tip is that you should never, ever read every word of ANY ACT Reading passage! At least, not as closely as you have been taught to do in school.
How can you read for concepts (not content) and still complete the questions in a timely manner?
This is where the "enlightened skim" comes in.
An enlightened skim is a couple of steps above what you're thinking when you say "skim."
Take a look at the example from a recent humanities group session attached below.
The goal of the enlightened skim is NOT to highlight important details. That takes time to process, and the first read-through should just get you from Point A to Point B.
No - the goal of the ES is to leave yourself "breadcrumbs" in the passage, to avoid having to hunt too long for the concepts. If you're not sure where things are located in the passage after your first read-through, you probably just need to refine your skimming techniques!
Remember that you will not have highlighters on the test, so I would recommend underlining, circling, stars beside key concepts. The highlighting just makes it easy to see for our purposes here.
What else would you add to this strategy?
