The ACT (American College Testing) is a standardized test used for college admissions in the United States. The test measures a student’s knowledge and skills in English, mathematics, reading, and science reasoning.

The ACT is composed of four multiple-choice sections: English (75 questions), Math (60 questions), Reading (40 questions), and Science (40 questions). The English, Math, and Reading sections are scored on a scale of 1-36, and the Science section is scored on a scale of 1-36. The overall composite score is the average of the four section scores, rounded to the nearest whole number.

In addition to the main test, there is an optional Writing section. The Writing section is an essay prompt that asks students to provide their own analysis of a given issue or topic. The Writing section is scored on a scale of 2-12 and is not included in the overall composite score.

The ACT is widely used by colleges and universities in the United States as part of their admissions process. It is typically taken by high school juniors or seniors, with scores being sent directly to the schools to which the student is applying.

Preparing for the ACT can involve studying materials provided by the test makers, taking practice tests, and working with tutors or taking courses. There are also many resources available online to help students prepare for the ACT.
