High school student here. I have just over a month until my AP Calculus exam. I love math and I'm confident that I understand all the concepts necessary to ace the exam. Here's the catch: Whenever I work with a ticking clock, I either don't finish every question in time or make a bunch of silly mistakes—the kind that leave you shaking your head and thinking, "I know that." This especially true of the multiple choice section. Working through the problem to a full, neat solution takes too long. Merely scribbling enough so that I know which circle to fill in leads to errors. How do I balance the two? Get faster at producing orderly work? Develop better intuition? Or something else entirely?
