The #1 thing to understand about ACT English
The ACT English test makes you an EDITOR
You are not answering questions about grammar in the abstract — you are improving 5 real passages. Every underlined portion needs to be judged: is it already correct, or does it need fixing? The most common wrong answer is changing something that was already right. Train yourself to defend "NO CHANGE" as confidently as any fix.
Why English matters so much
English is one of the four equally-weighted sections. Getting the fundamentals right moves the needle fast.

How to attack ACT English efficiently
Read the full sentence first
Never evaluate an underlined portion without reading the whole sentence — and often the sentence before and after. Context determines correctness.
Shorter is usually better
When two answers are both grammatically correct, the ACT almost always prefers the most concise version. If an answer adds words without adding meaning, eliminate it.
Defend NO CHANGE
"NO CHANGE" is correct roughly 25% of the time. Students who automatically distrust it lose easy points. Ask: "Is this sentence actually broken?" before changing anything.
