Electives are courses you get to choose, as opposed to required classes that every student must take. They appear in both high school and college, giving you room to explore subjects outside your mandatory curriculum. While elective credits are often required for graduation, the specific classes you use to fill those credits are largely up to you.
How Electives Differ From Required Courses
Every school has two buckets of coursework. The first is your required curriculum: the core classes everyone in your program must complete. In high school, that means specific credits in English, math, science, and social studies. In college, it includes general education courses (often called “gen-eds”) and major-specific requirements. A biology major, for example, might still need two semesters of English as part of their general education.
The second bucket is electives. These are the courses where you have real freedom. An engineering student might take a dance class. A history major might sign up for introductory computer science. You still need to earn a certain number of elective credits to graduate, but the subjects are your call.
Electives in High School
High school diplomas typically require a set number of elective credits alongside your core academic subjects. A common structure calls for around six elective credits out of roughly 22 total credits needed to graduate. Those electives can come from a range of categories: career and technical education (CTE), arts like music, theater, dance, or visual arts, world languages, ROTC, or additional coursework in traditional academic subjects.
Some high schools organize electives into tiers. You might be required to take a couple of elective credits from a specific group, such as CTE, arts, or world languages, and then fill the remaining elective slots with whatever interests you. Schools increasingly encourage students to build a “concentration” of four related elective courses in one area, which can signal a focused interest to college admissions offices or help develop a marketable skill set early.
Three Types of College Electives
College elective structures are more nuanced than high school. Most degree programs divide electives into three categories, and understanding the differences helps you plan your course schedule efficiently.
General Education Electives
These are entry-level courses designed to give you a working knowledge across broad subject areas: writing and communication, social sciences, natural sciences, and humanities. Your school’s gen-ed requirements will specify how many credits you need in each category, but you often get to pick which specific course satisfies each one. Choosing a psychology course versus a sociology course to fill a social sciences requirement, for instance, is an elective decision within a required framework.
If you earned qualifying AP or IB scores in high school, some of these general education requirements can be satisfied before your first semester even begins, freeing up space in your schedule for other electives.
Major-Specific Electives
These are courses within your declared major where you choose from a menu of options. A marketing major might pick between consumer behavior and digital analytics to satisfy the same requirement. These electives let you develop a deeper understanding of a specific corner of your field, which is especially useful if you’re aiming for a particular career path or considering graduate school in a specialized area.
Free Electives
Free electives are the most flexible category. These are credits that fall outside your required courses and your major, filling the gap between your mandatory coursework and the total credit hours your degree demands. A bachelor’s degree typically requires 120 credit hours, and after accounting for gen-eds and major requirements, you might have anywhere from 9 to 30 credits of purely free elective space depending on your program.
Any course that doesn’t count toward another requirement on your academic evaluation will apply here. This is where students explore completely unrelated interests, pick up a minor, or take skill-based courses like public speaking or personal finance.
Choosing Electives Strategically
Electives aren’t throwaway classes. How you use them can shape your resume, your skill set, and even your GPA. Here are a few practical approaches.
If you’re considering a career change or haven’t settled on a major, electives let you test the waters without committing. Taking an introductory accounting course as a free elective costs you nothing beyond the credit hours and can tell you quickly whether finance is a realistic path. Students who use electives to explore early are less likely to switch majors late, which saves both time and tuition money.
If your career goals are clear, stacking electives in complementary areas builds a stronger profile. A computer science major who takes electives in statistics and data visualization, for example, is more competitive for data science roles than one who chose courses at random. Similarly, a pre-law student who loads up on writing-intensive electives develops skills that directly transfer to law school.
Some students use free electives to pick up a minor, which typically requires 15 to 18 additional credits in a focused subject. If your free elective slots align with a minor’s requirements, you can earn the credential without adding extra semesters. Others use electives to build practical skills that don’t fit neatly into a major, like a foreign language, graphic design, or project management.
Do Electives Affect Your GPA?
Yes. Elective courses count toward your cumulative GPA the same way required courses do. This cuts both ways. A challenging elective where you earn a low grade will drag your GPA down, while an elective in a subject you enjoy and excel at can boost it. Some students deliberately choose one elective per semester in a subject they’re naturally strong in, balancing out tougher required coursework. Just make sure you’re still getting value from the class beyond an easy grade.
