Enhanced ACT Math gives you four choices, not five. A blind guess is 1 in 4, and knocking out one choice makes it 1 in 3. What the section covers is in what ACT Math tests.
Elimination is worth more than it used to be
Older paper forms had five options. Those habits undersell a crossed-out choice now. One elimination is a real lift. Two eliminations leave a coin flip. There is no penalty for a wrong answer, so an empty bubble is the only wasted shot. Guessing rules are in whether you should guess.
Do not backsolve five letters
If you plug choices in, you only have four to try, and they are often ordered. Start with a middle value when the choices are a list of numbers. Strategic guessing on this section is in guessing on ACT Math.
The bottom line
Four choices means you should never leave a Math item blank, and one solid elimination is enough to guess with a plan.
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.
