* Your grade level: Younger students typically have less choice than older students. Elementary school might have very little elective choice, while high school students often have significantly more options.
* Your specific K12 program: K12 offers various programs and pathways, and the degree of course selection available will differ between them. Some programs might be more structured than others.
* Your school's requirements: Even within a program, there will likely be required courses that you must take. Elective choices will fill in the remainder of your schedule.
* Availability of classes: The courses offered depend on teacher availability, resources, and student demand. A popular course might fill up quickly.
In short, you'll have *some* choice, but it's not entirely open-ended. It's best to consult your K12 program's course catalog and guidance counselor to determine the exact extent of your course selection options.
