100 hard-tier, hand-verified questions covering all four Bluebook®-style domains, selected around the error patterns Korean students most often miss: subtle contrast transitions, restrictive vs. nonrestrictive punctuation, subject–verb agreement across long intervening phrases, connotation-precise vocabulary, and multi-constraint rhetorical synthesis. Answer choices reveal the explanation immediately — study independently, in English, start to finish.
Each question is either a standalone passage with a blank to complete, or a passage followed by a question about its content, structure, or purpose. Read each passage and question carefully, then choose the best answer. Selecting a choice immediately reveals whether it is correct and why — use the explanation and hint to understand the underlying rule, not just the right letter.
