A useful Math checkpoint is about 15 questions every 15 minutes. That is a pace check, not a cap on every item. 50 minutes for 45 questions is about 67 seconds as a mean, in 67 seconds on Math.
Look up at 15, 30, and 45
Behind the checkpoint: skip more. Ahead of it: you have banked time for the back half, in the first-half sprint. Reading uses a passage checkpoint, in one passage every nine minutes.
Section clocks are in how long the ACT is.
The bottom line
15 questions, 15 minutes. Adjust if you are behind. Do not stopwatch each stem.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
