The ACT is accepted by most colleges as an alternative to the SAT college entrance exam.  While the format, scoring, timing and question types may be different than on the SAT, the skills and concepts tested are similar.

There is no penalty for guessing on either the SAT or ACT.  The ACT consists of four multiple choice sub-tests: English, Mathematics, Reading and Science. There is an OPTIONAL Writing Test.

The highest attainable score on each of the sub-tests is 36.  The  average of the four multiple choice tests is called the Composite Score, and the highest Composite Score attainable is 36.  The optional writing test is scored separately, and the highest attainable score is 12.  


The English Test

Measures knowledge of standard written English, grammar, usage and punctuation.

The Reading Test

The Reading Test contains passages from Prose Fiction, Humanities, Social Science and Natural Science. The Reading Test tests many specific and inferential reading skills: recognizing  central ideas and themes, seeing  relationships, drawing inferences and conclusions. The test also requires the student to analyze the author's word choice, and to use evidence presented to make connections between the different texts related to the topic.

The Science Test

This is a test that measures the interpretation of scientific data in the context of reading passages and graphic models. The Science test does NOT  permit the use of a calculator.
