Cheat Sheet

  1. Master Common Spelling Pitfalls -

    Review homophones and confusable words by memorizing tricks like "i before e except after c." For example, in a proofreading quiz you'd catch "their" vs. "there" by substituting words in the sentence to test meaning. Reliable sources like Merriam-Webster and Oxford Dictionaries list top misspellings to practice.

  2. Strengthen Subject-Verb Agreement -

    Brush up on rules ensuring singular subjects pair with singular verbs and plurals with plurals, e.g., "The team is" versus "The teams are." Purdue OWL's grammar guide provides clear charts and exercises that mirror proofreading test questions. Mnemonic: "One subject, one verb" helps you spot mismatches quickly.

  3. Refine Punctuation Usage -

    Practice placing commas correctly in compound sentences and after introductory phrases; for instance, "After reviewing the report, she approved it." The Chicago Manual of Style offers detailed examples to steady your comma confidence. Remember the FANBOYS (for, and, nor, but, or, yet, so) mnemonic to guide connecting independent clauses.

  4. Detect Passive Voice -

    Learn to convert passive constructions like "The draft was edited by Alex" into active ones: "Alex edited the draft." Cambridge University Press emphasizes active voice for clarity and conciseness, a common focus in proofreading practice quizzes. Ask "Who does the action?" to uncover hidden passives.

  5. Ensure Consistency with Style Guides -

    Follow a single style guide (APA, MLA, Chicago) for capitalization, numbering, and formatting; Platforms like the APA Style website offer free quick-reference sheets. Consistency in hyphenation (e.g., "well-being" vs. "wellbeing") is a frequent proofreading question. Keep a style sheet handy as you tackle a proofreading skills quiz to maintain uniformity.
