Editing Mastery gives your student a flawed sentence and one job: fix it. Capitals, end marks, commas, apostrophes, tricky homophones, run-ons, semicolons, who vs. whom — 48 skills climbing from beginning editing (about third grade) to advanced high-school usage.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eA short placement test finds the right starting level in minutes. Every skill opens with its rule, plainly stated.
