High school courses fall into two broad buckets: required core classes you need to graduate and electives you choose based on your interests. Most students take between six and eight courses per year across four years, building a transcript that includes English, math, science, social studies, and a mix of other subjects. Understanding how these courses work helps you plan a schedule that meets graduation requirements while keeping your options open for college or a career.
Core Classes Required for Graduation
Every state sets minimum credit requirements in four main subject areas. One credit typically equals one full-year course, so “4 credits of English” means four years of English classes. Here’s what most students can expect:
- English: Nearly every state requires 4 credits. You’ll move through courses like English 9, English 10, American Literature, and British Literature, or variations with similar names. Each year focuses on reading comprehension, writing, grammar, and literary analysis, with complexity increasing as you advance.
- Math: Most states require 3 credits, though some require 4. A common sequence is Algebra I, Geometry, and Algebra II. Students who move faster may take Precalculus or Calculus in their junior or senior year.
- Science: Requirements range from 2 to 4 credits depending on your state, with 3 being the most common. Typical courses include Biology, Chemistry, and Physics. Some schools also offer Earth Science or Environmental Science.
- Social Studies: Most states require 3 credits, though requirements range from 2 to 4.5. Courses usually cover U.S. History, World History, Government, and Economics.
Beyond those four subjects, most schools also require credits in physical education, health, and sometimes fine arts or a world language. The total number of credits needed to graduate varies, but it commonly falls between 22 and 26. Your school counselor can tell you the exact breakdown for your district.
Elective Courses
Electives are courses you pick yourself, and they make up a significant chunk of your schedule. After accounting for required classes, most students have room for one or two electives per year, sometimes more. These let you explore subjects you’re curious about or build skills for a future career.
Common elective categories include:
- Visual and performing arts: Drawing, painting, photography, graphic design, drama, choir, band, orchestra, art history
- World languages: Spanish, French, German, Mandarin, American Sign Language (many colleges expect at least two years of the same language)
- Business and technology: Accounting, business management, entrepreneurship, computer science, journalism
- Life skills and social sciences: Psychology, sociology, speech and debate, childcare, nutrition
Some electives are standalone one-semester classes, while others build over multiple years. A student who takes Photography 1, for instance, might continue to Photography 2 or Advanced Photography. Electives also matter for college applications because they show admissions officers what you care about outside of required coursework.
Course Difficulty Levels
Most high schools offer the same subject at different difficulty levels. The labels vary by school, but the general tiers look like this:
- Regular (or “college prep”): The standard version of a course. It covers all the essential content at a steady pace and is appropriate for most students.
- Honors: A step up in depth and workload. Honors courses move faster, assign more reading and projects, and explore more complex ideas. They often attract students who want an academic challenge and tend to have more discussion-based classroom environments.
- Advanced Placement (AP) and International Baccalaureate (IB): The most rigorous options, designed to mirror college-level work. More on these below.
Many schools weight grades from harder courses when calculating your GPA. An A in an honors or AP class might count as a 5.0 instead of a 4.0, which is why you’ll hear the term “weighted GPA.” This rewards students who take on tougher coursework even if they don’t earn a perfect grade in every class.
Advanced Placement and IB Courses
AP and IB courses are the most academically demanding options in most high schools, and they can earn you actual college credit before you graduate.
Advanced Placement courses are run by the College Board. You can take individual AP classes in subjects that interest you, like AP Biology, AP U.S. History, or AP Calculus. At the end of the year, you sit for a standardized AP exam that costs $94. Each college decides what score it considers passing (usually a 3, 4, or 5 on a 1-to-5 scale) and how many credits it will award.
The International Baccalaureate program takes a different approach. Rather than individual classes, IB is typically a two-year diploma program during junior and senior year that covers six subject areas plus additional requirements like a long research essay and community service hours. IB exams also happen at year’s end. The program can be more expensive, with registration and exam fees reaching several hundred dollars, though fee waivers are available for students with financial need. Not every school offers IB, and it’s less widely available than AP.
Both AP and IB courses carry weighted grades and signal academic rigor to college admissions offices.
Dual Enrollment Courses
Dual enrollment lets you take actual college courses while still in high school, earning credit that counts toward both your high school diploma and a future college degree. You might attend classes at a nearby community college, take them online, or have a college instructor teach at your high school.
The key difference from AP and IB is how you earn the credit. With AP or IB, your college credit depends on a single end-of-year exam score. With dual enrollment, your credit is based on the grade you earn throughout the semester, just like a regular college class. That grade also becomes part of your permanent college transcript, so a poor performance follows you. A strong performance, on the other hand, gives you a head start on your degree.
Cost varies widely. Some states cover dual enrollment tuition entirely for public high school students, while others charge reduced rates. If flexibility matters to you, online dual enrollment courses let you work around extracurriculars, a job, or other commitments.
Career and Technical Education
Career and Technical Education, usually called CTE, offers hands-on courses organized into career pathways. Instead of purely academic content, CTE classes teach job-ready skills in a specific field. Common pathways include:
- Health sciences: Medical terminology, anatomy, safety and first aid, ethics in health care
- Skilled trades: Construction technology, automotive repair, welding, cabinet manufacturing
- Business: Entrepreneurship, accounting, business law
- Agriculture: Agricultural science, animal care, environmental management
- Information technology: Programming, networking, cybersecurity
- Education: Early childhood education, teaching fundamentals
CTE pathways typically span two or three years and may include apprenticeships or internships. Some programs award industry certifications alongside your high school diploma. CTE is not a lesser track. Many students combine rigorous academic courses with a CTE pathway to graduate with both college readiness and a marketable skill.
How to Build Your Schedule
Freshman year is mostly spoken for. You’ll take the first level of each core subject plus a few electives or required extras like physical education. The real choices open up in sophomore through senior year as you fulfill requirements and free up slots for electives, AP classes, or CTE pathways.
When planning, think about your goals. If you’re aiming for a competitive four-year college, loading up on honors, AP, or IB courses and taking at least two years of a world language will strengthen your application. If you want to enter a trade or start working right after graduation, a CTE pathway paired with solid core classes gives you practical credentials. Many students blend both approaches.
Your school counselor is the best resource for mapping out a four-year plan. They can confirm your state’s graduation requirements, help you choose between honors and regular sections, and make sure you’re not missing prerequisites for courses you want to take later. The earlier you start planning, the easier it is to fit everything in.
