Students can take practice science exams for AP tests at CollegeBoard.org, for the ACT at ACTStudent.org and for Virginia grade level competency at Jefferson Lab. The appropriate practice science exam depends on the student's age and preparatory needs.
Seven sets of science questions can be found on the ACTStudent website. At CollegeBoard, students can take practice science exams in several AP categories, including biology, chemistry and environmental science. For competency tests, Jefferson Lab allows students to select the number of questions they want to answer between five and 40. Science tests are available for biology, chemistry and earth science, as well as earlier grade levels.
