The 50-Minute Clock: 45 Items at 67 Seconds Each

The 67 second average feels tighter than it sounds because it is an average, not a rule. Early items are usually quick and straightforward, which banks you extra seconds for the harder items waiting near the end. The clock does not care which item you are on, so the real skill is tracking checkpoints rather than timing each question individually.

Budget by checkpoints, not by the stopwatch on every item. A steady pace puts you through 9 items every 10 minutes, since 45 items over 50 minutes scales directly with however much time has passed. At the 25 minute mark, halfway through the clock, you should be about halfway through the items too. If you are behind at a checkpoint, that tells you to move faster on the next stretch, not to panic on the current item.

This pacing logic is what makes the four-choice guessing strategy and the no-formula-sheet reality work together. Since every item is worth the same single point regardless of difficulty, time is the only resource you control, and it should flow toward items you can actually answer rather than get stuck defending one hard problem. That same logic explains why leaving items blank is the one guaranteed way to lose points you could have had just by marking a guess.
