SAT

SAT flashcards from your notes and prep books

Paste a vocab list, upload a prep-book chapter, or drop in your math formula sheet and get back a deck of SAT-style cards for the digital test. Cover vocabulary in context, grammar rules, and the formulas you need to recall fast on the Math section.

How to actually use it

01Build vocabulary-in-context cards

The digital SAT tests vocabulary in context rather than obscure word lists, so the best cards pair a word with a sentence that shows its meaning. Paste a word list or a set of Reading & Writing practice sentences and Deckio generates cards with the word, a clear definition, and an example sentence — the format that actually transfers to test questions.

02Turn grammar rules into recall cards

The Writing portion tests a predictable set of rules: subject-verb agreement, pronoun-antecedent agreement, comma and semicolon use, modifier placement, parallel structure. Paste your grammar notes and Deckio makes one card per rule with a quick correct/incorrect example, so you recognize the tested error instantly.

03Make a math formula deck

The Math section provides some formulas but rewards instant recall of many others — slope, the quadratic formula, circle equations, special right triangles, exponent rules. Upload or paste your formula sheet and Deckio generates cloze and Q&A cards so the formulas are automatic on test day.

Why SAT prep rewards flashcards

The digital SAT is adaptive and tightly timed, so hesitation costs points. Instant recall of vocabulary in context, grammar rules, and math formulas frees up the seconds you need to reason through each question. Active recall with flashcards is the proven way to build that automaticity.

Rereading a prep book feels productive but rarely builds fast recall, and making cards by hand for every rule and formula is slow. Generic SAT decks help but do not target the specific questions you personally miss.

Deckio gives high schoolers a faster path. Paste your list or upload your chapter, get a draft deck in minutes, trim it to your weak areas, and review a little each day. Spaced repetition handles the scheduling so you remember it on test day, not just the night you studied it.

Who this is for

Vocabulary in context
Generate cards from a word list or practice-passage sentences and review a set each day.
Grammar rule drilling
Build a deck of the tested writing rules with correct/incorrect examples so you spot errors instantly.
Math formula recall
Turn your formula sheet into cloze cards so every formula is automatic under time pressure.

What it looks like

Input

The slope of a line through points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1). The quadratic formula solves ax^2 + bx + c = 0: x = (-b plus or minus the square root of (b^2 - 4ac)) / (2a). A 30-60-90 right triangle has side ratios 1 : square root of 3 : 2.

Generated cards

Formula for the slope of a line through two points?

slope = (y2 - y1) / (x2 - x1)

State the quadratic formula.

x = (-b ± √(b² - 4ac)) / (2a), for ax² + bx + c = 0.

Side ratios of a 30-60-90 triangle?

1 : √3 : 2 (short leg : long leg : hypotenuse).

Generic SAT decks are convenient but cover words and rules you may already know, and building cards by hand is slow. Deckio generates vocab, grammar, and formula cards from your own notes in minutes, so you review exactly what your practice tests show you are missing — with spaced repetition doing the scheduling.

Questions

Is this built for the digital SAT?+

Yes. The cards work the same regardless of format — vocabulary in context, grammar rules, and math formulas are all tested on the digital SAT, and flashcards build the fast recall the adaptive, timed format rewards.

Does the SAT still test hard vocabulary?+

The digital SAT tests vocabulary in context rather than obscure word lists, so Deckio generates cards that pair each word with an example sentence — the way the test actually checks meaning.

Can I make math formula cards?+

Yes. Paste or upload your formula sheet and Deckio generates cloze and Q&A cards for slope, the quadratic formula, circle equations, special triangles, and more.

Can I export to Anki?+

Yes. Any deck exports as an .apkg file for Anki. Export is available on Pro, Ultimate, and during the 7-day trial.

Is the free tier enough?+

Free gives 100 AI credits per month — enough to try it out. Full prep usually fits Pro (1,500 credits/month) or the one-time Starter pack (500 credits, $4) for a lighter budget.

Can my whole study group use one deck?+

Yes. Share any deck via public link so your study group reviews the same cards. Many students split deck-building across friends and share.
