The ACT is achievement test that measures what students have learned in school.
The basic ACT exam includes four parts: English, reading, mathematics and science. An optional writing test also is available.
Some colleges require or recommend a writing score, but many do not. To find out if a writing score is required by particular colleges, student may visit the ACT's Web site for a searchable list, or students may contact colleges directly. ACT scores are accepted by virtually all colleges across the nation.
Some students perform better on the ACT than on other college entrance exams because it is based on achievement, not aptitude. The basic exam takes three hours to complete, plus an additional 30 minutes for those who opt to take the writing test.
The basic registration free for the ACT is $29. An additional $14 fee is required for students who choose to take the ACT writing test, bringing the total registration fee to $43 for these students.
