If a Math item is still a wall after about a minute, flag it and move. The next five easier points are worth more than one stuck item. Math is 45 questions in 50 minutes. Two-pass order is in the two-pass method.
A minute is a budget, not a dare
You can return. The first half of the section is usually faster, in the first-half sprint. On the digital test, flagging is a tap, in flagging questions.
Guessing whatever is still blank is in guessing on the ACT.
The bottom line
One minute of no progress: flag, skip, come back if time is left.
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.
