Vocabulary Study Doesn't Have to Be Painful

Most test prep vocabulary tools are flashcards that test recognition, not recall. But the SAT and GRE test whether you know the word — not just recognize it.

Flashcards Only Test Recognition

Seeing a word and picking a definition is passive learning. You recognize it on a card but can't use it in context — or spell it when it counts.

Spell Again makes you actively produce each word — hear it, spell it, learn it.

Generic Word Lists

Many "SAT word lists" haven't been updated since the paper SAT. The Digital SAT tests different vocabulary than the old format.

Curated from high-frequency words on the Digital SAT (2024+), current GRE, and ACT.

No Progress Tracking

How do you know which words you've actually mastered vs. ones you keep forgetting? Most vocab apps don't tell you.

Per-word mastery tracking shows exactly which words need more practice.

Curated Lists for Every Major Test

Each list is organized by test and difficulty tier. Words that appear on multiple tests are tagged so you can study efficiently.
