The SAT and ACT are two very different college entrance exams. Both are nationally administered and are used to help colleges evaluate applicants.
The SAT is essentially a three-part aptitude test (Reading, Math, Writing) while the ACT is more of an achievement test with four core sections (English, Math, Reading, Science) and an optional Writing section.
Most colleges will accept either or both exams. A handful of colleges require one (typically the SAT).
The SAT vs. ACT chart below will help you understand the structure and content of both exams.
