If your ACT prep routine is “read the passage again until it clicks,” I want to gently interrupt you.
Rereading feels like studying. Your eyes move across the text, the words feel familiar by the third pass, and that familiarity gets mistaken for mastery. But familiarity and retention are not the same thing, and the research on this is not close.
In a now-classic study, Roediger and Karpicke had college students learn passages one of two ways: rereading them repeatedly, or reading once and then testing themselves on the content. A week later, the self-testing group remembered significantly more than the rereading group, even though the rereading group had felt more confident right after studying.
For ACT prep, this translates directly. Instead of rereading a passage until it feels familiar, close it and try to summarize the main argument from memory. Then go back and check yourself. It will feel harder and less certain in the moment. That discomfort is the part that’s actually building retention.
Small shift, real payoff, especially with a test date on the calendar.
