Search for a course via the search bar, or browse by subject, level (from college and professional development to high school, middle school, preschool, and more), or goals (test prep, college research, professional licensure, and more). For example, tap Science and a list of 677 science-related courses appear. Then filter courses by level, subtopics within science, and goals. Choose the course. Take an optional pre-test in the course. Begin the course by watching or reading the first lesson. Take an optional end quiz. Downloading content is optional. High school students interested in earning college credit can choose from 150 courses that more than 1,500 colleges and universities will accept (though it's best to check with your chosen college first): General education courses are usually easiest to transfer. Parents can see the list of courses and the syllabi and preview videos before subscribing.
