Concept 3

Use correct comparative/superlative forms and logical comparisons.

Core Idea

Use a comparative for two things, a superlative for three or more, and make sure the sentence compares like with like.

Understanding

Rule: Some ACT errors sound subtle because the comparison word is only slightly off. "Best" looks strong, but it is wrong if the sentence compares only two options.

Also make sure the sentence does not compare unlike things, such as a student to a sentence or a city to a bus route.
