What’s the difference between the SAT & the ACT?
do all colleges accept the ACT?…is there an essay on the ACT?…. do you get more time for the ACT??… etc.

thank you

According to the ACT’s website:

“The ACT is an achievement test, measuring what a student has learned in school. The SAT is more of an aptitude test, testing reasoning and verbal abilities.

The ACT has up to 5 components: English, Mathematics, Reading, Science, and an optional Writing Test. The SAT has only 3 components: Critical Reasoning, Mathematics, and a required Writing Test.

The College Board introduced a new version of the SAT in 2005, with a mandatory writing test. ACT continues to offer its well-established test, plus an optional writing test. You take the ACT Writing Test only if required by the college(s) you’re applying to.

The SAT has a correction for guessing. That is, they take off for wrong answers. The ACT is scored based on the number of correct answers with no penalty for guessing.

The ACT has an Interest Inventory that allows students to evaluate their interests in various career options.”

Out of personal experience, I found that the ACT was easier than the SAT, but that is my opinion only. The ACT gives you an option of taking the essay or not while you have to take it on the SAT. In regards to time, they both are about the same, with some subtle differences.
