The AP English Language exam in 2027: format, date and length

This passage was written for this course. It imagines an essay that a university professor who studies memory writes for a general-interest science magazine.

Every semester, a student stays after my first lecture to ask how she can stop forgetting things. She has usually just lost an argument with a textbook, or a name, or the location of her car keys, and she wants a technique. I give her a few. Then, because she has asked the wrong question and I am fond of her for asking it, I tell her that forgetting is not the opposite of memory. It is part of how memory works.

This sounds like the kind of thing a professor says to seem profound, so let me be concrete. Picture the parking lot where you left your car this morning. You can probably find the spot. Now try to recall where you parked on the third Tuesday of last month. Unless something unusual happened that day, the answer is gone, and good riddance. A brain that kept every parking space with equal vividness would present you, each evening, with hundreds of competing spots, and you would stand in the lot like a diner at a buffet who cannot choose. Losing the old spaces is what lets you find today's.

The same principle operates at larger scales. When you learn what a dog is, you do not store every dog you have met; you keep something like a sketch, and you let most of the particulars go. That loss is the price of the category. A child who remembered each dog perfectly, and could never let the details blur, might struggle to arrive at the idea of "dog" at all, because no two dogs would ever seem enough alike to share a name. To think, in this sense, is partly to forget.

Memory is also less like a filing cabinet than like a story retold. Each time we recall an experience, we rebuild it from pieces, and the rebuilt version is what we keep. This is why two siblings can remember the same holiday so differently, and why a story told often can drift away from the event it began as. That drift is unsettling. It means that the vivid scene you would swear to in a courtroom may have been quietly edited by the very act of remembering it. But the same flexibility lets old experience bend to fit new situations, so that what you learned in one kitchen helps you cook in another.

None of this is a reason to celebrate every lapse. Some forgetting is illness, and anyone who has watched a parent lose the names of her children knows that it is not a feature to be admired. Nor does the usefulness of forgetting excuse the student who never reviewed her notes. My claim is narrower. A healthy memory is selective by design, and its selection is not a flaw we tolerate but the work that memory exists to do.

So when the student asks how to stop forgetting, I suggest that she ask instead what she wants to keep. She can choose to return to a fact, to test herself on it, to connect it to something she already knows, and her brain will treat that fact as worth saving. The rest she can let go. The rest, after all, is mostly last month's parking spaces.
