Problem
I. Review, if it's timed right, will help you remember enough to get through the test successfully, even if that knowledge doesn't stick in the long term.
II. Review is a strategy to trigger memory because it may have been a month or so since you did your first reading of the text.
III. Review is an active reading technique that helps you more deeply understand and make connections with the material, especially as a last step after you've used other active reading strategies.
IV. Review is a way of double checking that you aren't forgetting the key answers you marked in the text.
