You probably can. Check with the individual college. Each college or college system can usually set their own rules as far as whether or not they have a minimum age. Ironically my son, who took his first college course after high school freshman year, took a regular course at a college that didn’t have a minimum age limit BECAUSE he was rejected at a college program for high school students that wouldn’t admit students who hadn’t completed grade 11.

Also check or have your parents check the policies in your school district. Many are required to pay for your college course if you’re qualified to take it and the school doesn’t offer it.

Also note that many big name universities offer online classes, including the Ivy League universities, and completing a course at a better college will be more meaningful than a course taken at a community college with respect to college admissions.
