Correct: on Monday.<\/li>\n<li>Incorrect: on 7 o&#8217;clock. Correct: at 7 o&#8217;clock.<\/li>\n<li>Incorrect: at July. Correct: in July.<\/li>\n<li>Learn fixed expressions as chunks because not every use follows a simple physical rule.<\/li>\n<\/ul>\n<h2>Prepositions Quick Review<\/h2>\n<p>Before you move to the practice section, review the key patterns above and pay special attention to the examples and common mistakes.
