The ACT gives you no formula sheet. Every formula you need — from the quadratic formula to the Law of Cosines — has to be in your head before you sit down. That’s a problem for a lot of students, and it’s exactly why we built the ACT Math Flashcards.
57 free cards. Every formula and concept that shows up on the ACT Math section. No login, no email, no paywall.
What’s Covered
The cards span all six ACT Math content areas: Number & Quantity, Algebra, Functions, Geometry, Statistics & Probability, and Applied Math. You’ll find the essentials like slope, the Pythagorean theorem, and SOHCAHTOA alongside higher-level material like logarithm rules, trig identities, and the Law of Sines and Cosines.
Every card is tagged with a score range — foundational (13–23), proficient (24–32), or advanced (33–36) — so you can focus on what actually moves your score instead of drilling material that’s either too easy or too advanced for where you are right now.
How It Works
The flashcard tool is fully interactive. Filter by content category, filter by score range, flip cards to reveal formulas, and hit “I know this” to pull mastered cards out of your deck. Each session automatically tightens around what you still need to learn.
Short daily sessions work far better than marathon cramming — ten minutes a day for two weeks will do more for your score than two hours the night before the test.
Formulas Are the Floor, Not the Ceiling
Memorizing a formula is step one. Knowing when to use it under timed pressure is what separates a 26 from a 30. Once you’ve worked through the flashcards, pair them with the ACT Math practice drills — 22 drills covering every content area, each with five questions and full explanations. That combination of formula recall plus applied practice is what builds real test-day readiness.
