@chillyee just wanted to say that if your lowest score is between a 27 and 30, you’re doing awesome! But as for tips, Kaplan’s ACT prep book has a great section for punctuation rules on commas, periods, semicolons, colons, etc. I believe a great way to prepare for English is to practice. Unlike the math section, there’s only so many types of questions they can ask. Depending on what you feel you struggle with most, it may be worthwhile to review idioms and rhetorical/style questions heavily, as people commonly have trouble with these. (These are those “does this passage meet the goal of being a persuasive essay about why students should abandon cell phone usage?” with the two “yes…explanation” and two “no…explanation” answer choices, as well as commonly introverted words like lay/lie, who/whom, etc). I earned a 36 on the September 2014 English ACT and a 35 on the March 2015 English ACT by reviewing that book. Let me know if you have any specific questions or anything I can help you with!
