I think that note-taking on Verbal is only useful
when you use it as a tool to aid understanding, instead of memory. The passage or argument stays on the screen, so why bother taking notes to aid your memory? You can always look back at the relevant parts of the passage instead of looking at your notes, and it'll probably be quicker, too.
But the reason I and many of my students take notes at least sometimes on Verbal, is because
good note-taking can help you wrap your head around a passage. Try taking notes in the form of a flowchart, diagram, or table. Try taking notes on what you figure out about the passage as you read it, as opposed to the actual content of the passage. Take notes that are structured in the same way you want to structure your thinking.
For example, maybe you're reading the argument that goes with a 'find the assumption' CR question. You might jot down the conclusion in shorthand, or possibly just the abbreviation 'concl', in the middle of your paper. Then, use arrows and bubbles to show how each piece of evidence leads to the conclusion. Some pieces of evidence may help directly prove the conclusion, while others might have to be combined together, or might help support each other. You'll end up with something that looks a bit like a spiderweb on your paper. And when you're looking for the answer, you'll remember that the right answer (the assumption) could go 'in the gap' between any of the premises, and the conclusion.
In short: take notes, but not how you did it in high school! If you're writing down what the passage
says, or key terms/etc., you may very well be wasting your time. But in the end, try multiple note-taking approaches (including this one), and use what works for you
