How unit tests work
The ACT is a national college admissions test, accepted alongside the SAT by essentially all U.S. four-year colleges, that was restructured beginning in 2025 into an 'enhanced' format. The core exam now covers three required sections: English, Math, and Reading. English tests grammar, usage, punctuation, sentence structure, and rhetorical skills across passages; Math spans pre-algebra through algebra II, geometry, and a small amount of trigonometry, and now offers four answer choices per question rather than five; Reading measures comprehension and inference across prose, social science, humanities, and natural science passages. The headline change is that the Science section is now optional: it no longer counts toward the composite and instead yields a standalone Science score plus a STEM score that averages Math and Science. An optional Writing (essay) section remains available for schools that want it. The enhanced test is shorter than the legacy version and gives students noticeably more time per question, with shorter English and Reading passages and tighter, less word-heavy Math problems. The composite is the rounded average of English, Math, and Reading only. Students commonly stumble on ACT pacing, which is brisker than the SAT despite the added time, and on the Reading section's volume of detail under time pressure. Others lose points by neglecting the now-optional Science section when their target programs recommend it, or by misjudging whether to add Writing. Preparation should focus on official ACT practice in the enhanced format, grammar rules for English, and timing drills, since speed and accuracy together drive the composite.
Three required sections — English, Math, Reading — with optional Science and optional Writing. Core testing runs about 125 minutes; opting into Science adds roughly 40 minutes and Writing adds about 40 minutes.
English, Math, and Reading are each scored 1-36 and averaged (rounded) into the 1-36 composite; optional Science yields a separate 1-36 score and a STEM score, and Writing is reported separately.
