Adaptive skill practice — find your level, get sharper.

Writing practice

Build essays that argue, organize, and revise well
The editing-and-judgment side of strong writing — picking the sharpest thesis, the most relevant evidence, the logical paragraph order, the transition that fits, and the revision that improves a draft, plus rhetorical purpose, audience, and tone. Every item is multiple-choice: you judge and improve writing rather than produce an essay, so each has one defensible best answer. Aligned to the writing skills tested on the SAT, ACT, GRE, GMAT, and GED — not free-text essay scoring. Distinct from Grammar (the rules) and Clear Communication (sentence-level concision).
• Meets you at your level — never too easy, never too hard.
• Adapts every question to how you’re doing.
• Tracks your level over time. Skill practice, not a test.
