Some individuals take college-level courses enrolling in a college or university to accumulate a range of credits across subjects and interests. Keep in mind that the courses you select should contain a number prefix of 100 or greater, which means they are college-level. Generally courses that have course numbers starting with a zero or numbers less than 100 are considered developmental courses, or courses that prepare students for college-level courses. While these courses will not count toward your degree requirements, they are great "refresher" courses to help improve your math and writing skills (and increase the likelihood of success) when you do take regular college courses.
