🧠 Pro Tips for ACT English

💡 Shortest Answer Rule: If you're stuck between two choices, the shortest answer is usually correct. ACT prefers concise writing.

💡 "Being" is Almost Always Wrong: If an answer choice has "being", it's usually incorrect. It sounds awkward and passive.

💡 Trust Your Ear: If a sentence sounds wrong when you read it aloud, it probably is wrong.

💡 Use Process of Elimination: Even if you don't know the exact rule, eliminate 1-2 wrong answers to improve your odds.

💡 Check for "NO CHANGE": The original sentence is sometimes correct. Don't automatically change it.

💡 Watch for Redundant Words: Phrases like "advance warning" or "unexpected surprise" are redundant and often wrong.

❌ Common Mistakes to Avoid

• ❌ Using apostrophes for plurals (it's a common trap!)
• ❌ Choosing "being" unnecessarily
• ❌ Ignoring the "NO CHANGE" option
• ❌ Not reading the entire sentence before answering
• ❌ Choosing the longest answer (it's usually wrong)
• ❌ Rushing through punctuation questions
