The responsibilities of an ACT tutor revolve around helping students prepare for the ACT exam. In this career, you teach students how to prep for the test, facilitate practice tests, and teach strategies for test taking. Your duties include offering advice and practice for math, science, and English, as well as any other subjects with which a student needs assistance. Your exact role may depend on where you work. ACT tutors in high schools may follow a general test prep plan, while those in tutoring centers and private tutors may focus only on a student's needs.
