Enhanced ACT Math has four choices, A through D. Older five-choice practice overstates how long a guess takes. Section length is in how long the ACT is.
Guess among fewer leftovers
Crossing off one wrong answer now leaves three, not four. Crossing off two leaves a coin flip. Kill the impossible ones before you compute, in eliminate before you compute.
When the stem is an equation in x, plug a choice in, in plugging in answers. Start with a middle letter, in start in the middle.
The bottom line
Four choices. A random guess is 25 percent, and a two-choice guess is 50.
