The vast majority of ACT questions are not tricky or convoluted; the most obvious answer is generally the correct one (the exceptions to this rule are the 15-20 questions at the end of the Math section, which include a number of multi-step and/or complicated problems). Typically, the answer that makes the most sense is the correct answer. So feel confident eliminating “obviously wrong” or extreme answers. Correct answers tend to be mild in nature rather than harsh and absolute. Eliminate as many as possible by putting a single slash through the letter (not through the entire answer).
Removing as many wrong answers as possible makes it much easier to find the right answers. With the answer choices that remain, go deeper. Look for a word or words that make the answer wrong. Every word must be correct for an answer to be correct! As you can see, the more answer choices you eliminate, the easier the mining process will be.
If a question really confuses you, analyze the answers instead! Look for strategic solutions. For example, if two answers are exact opposites, one of them is likely to be the correct answer. The ACT is a very logical test, and it is that very logic that can be used to help you make it more predictable.
