Process of elimination on the ACT is crossing out answers that cannot be true, then guessing among what is left. There is no wrong-answer penalty, so a reduced guess is always better than a blank. On the digital test, use the answer eliminator instead of mental notes.
English
Kill anything that is wordier without a reason, or that breaks a punctuation rule you know. "NO CHANGE" is a real option—do not eliminate it for sport.
Math
Four choices (A–D). Cross out units that do not match, values that are the wrong sign, and answers you get by solving the wrong question. Plug in when the algebra is ugly: plug in answers.
Reading
Extreme words, claims from the wrong paragraph, and half-right choices go first. What remains should be the smallest claim the passage supports: how to answer Reading questions.
Digital tool
Strike through choices so you do not re-read them. Digital ACT tools.
The bottom line
Eliminate, then guess. A two-choice coin flip is a skill. A blank is a zero.
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.
