The ACT is a national college admissions examination that consists of subject area tests in: Science, Reading, English, and Mathematics. There is also an optional Writing test required by some schools. The Science test is composed of 40 multiple-choice questions which must be completed within 35 minutes. The questions in this section are drawn from the following academic areas: biology, physics, chemistry, Earth science, and space science. There are three specific types of questions: Data Representation, in which you interpret the information found in tables and charts; Research Summaries, in which you critique the design of an experiment and analyze the results; and Conflicting Viewpoints, in which you compare and attempt to reconcile divergent hypotheses.

The English test is composed of 75 multiple-choice questions, which must be answered within 45 minutes. These questions will cover punctuation, grammar and usage, sentence structure, rhetorical strategy, organization of text, and style. Your score in the English section will be the combination of your subscores on the Usage/Mechanics section (including punctuation, grammar and usage, and sentence structure questions) and the Rhetorical Skills section (including strategy, organization, and style questions).

The Mathematics test is composed of 60 multiple-choice questions, which must be answered within 60 minutes. The questions on this test are drawn from the following academic content areas: pre-algebra, algebra, geometry, and trigonometry. You will be allowed to use a calculator, and you will not be required to remember complicated formulae. The Reading test is composed of 40 questions, which must be completed within 35 minutes. The questions in this section are based on four prose passages of the following types: social studies, natural sciences, humanities, and fiction. The questions will require either recall of specific information from the text or interpretation of the ideas in the text. Finally, those students who take the ACT Plus Writing must complete one writing exercise within 30 minutes. The prompt will outline a controversial issue and give two conflicting opinions on it. You will then be asked to articulate your own position on the subject.

ACT results are accepted by all four-year colleges and universities in the US.

The ACT test is held 6 times a year in North America and 5 times in other regions. The specific test time for the Hong Kong test center is April, June, September, October and December.
