Grades 9–12·GPA, AP, IB, dual enrollment·Checked Oct 2026

What you do in grades 9–12 shapes your options after graduation more than any single test. Here is how GPA, course choices and activities actually count, using national data from college admission offices rather than rumors.

What each year of high school is for

A typical path for a student aiming at a four-year college. Your school counselor can adapt it to your goals.

  1. Step 1

    Build strong habits

    Your GPA starts here. Take the most challenging core classes you can do well in, and try a few activities.

  2. Step 2

    Add rigor

    Consider honors, AP or dual enrollment if offered. The PSAT 10 is optional practice.

  3. Step 3

    Test and research

    PSAT/NMSQT (the National Merit year), the SAT or ACT if your colleges use them, college visits and a balanced list.

  4. Step 4

    Apply and decide

    Early deadlines in October–November, FAFSA from October 1, decisions in winter and spring, and most colleges' reply deadline on May 1.

  5. Goal

    College, training or work

    A four-year college, community college, career training, the military or a job — all start from the same diploma.

Community college and career training are full options, not fallbacks. See College & Money for costs and transfer.

Grades

How GPA works

Colleges usually look at GPA on a 4.0 scale. Some high schools weight AP and honors classes higher; many colleges recalculate GPAs, focusing on core subjects (English, math, science, social studies, world languages) and adjusting or removing extra weighting, because grading scales differ between schools.

In practice: an A in a hard class counts for more than a number on your transcript suggests, and a weighted 4.3 from one school is not automatically "better" than an unweighted 3.9 from another. Colleges see your school's profile and course offerings alongside your grades.

Course rigor

Honors, AP, IB and dual enrollment

Four ways to take harder courses. Which ones you can choose depends on your school; each college decides its own credit rules.

HonorsHarder versions of regular courses, set by each high school. Many schools weight honors grades in their GPA.
Advanced Placement (AP)College-level courses with a College Board exam scored 1–5 per exam. Each college decides which scores earn credit or placement; many give credit for 3 or higher. The 2027 exam fee is $99 at U.S. schools, with a $37 reduction for students with financial need. Fees · All AP courses
International Baccalaureate (IB)A two-year diploma program in grades 11–12. Six subjects graded 1–7, plus up to 3 points for Theory of Knowledge and the Extended Essay. Creativity, Activity, Service (CAS) earns no points but must be completed. At least 24 points plus other conditions are needed for the diploma. IB
Dual enrollmentReal college courses, often at a community college, that can count for high school and college credit. More than 3.1 million high school students took one in 2024–25. Up 10% from 2.8 million in 2023–24 and 24% from 2.5 million in 2022–23. Community colleges taught about 70% of dual enrollment students. CCRC (IPEDS data)

What colleges actually weigh

NACAC asked four-year colleges how much each factor matters (Fall 2023 admission cycle, 185 four-year colleges). Grades and course choices dominate; test scores matter most at a small, often highly selective group of colleges.

FactorShare of colleges giving each factor 'considerable importance'
Grades in college-prep courses76.8%
Grades in all courses74.1%
Strength of curriculum63.8%
Positive character attributes28.3%
Essay or writing sample18.9%
Student's interest in attending15.7%
Counselor recommendation11.9%
Teacher recommendation10.8%
Extracurricular activities6.5%
Class rank5.5%
Admission test scores (SAT, ACT)4.9%

Senior year

Early Decision, Early Action or Regular Decision?

Early applications are usually due in October or November, with decisions in December or January. Most colleges give admitted students until May 1 to accept.

Early Decision (ED)Binding: apply to only one college ED; if admitted with enough financial aid, you must attend. Some colleges offer two rounds (ED I and ED II). Not a fit if you need to compare aid offers.
Early Action (EA)Non-binding: apply early to several colleges, hear back early, and still decide by spring.
Regular Decision (RD)Non-binding: apply by the regular deadline and get a decision later in the year.

State and college rules

Requirements depend on where you live and apply

Each state, and often each district, sets its own graduation requirements. NCES's 2018 state table shows state-required course credits from 11 (Maine) to 24 (in a dozen-plus states and DC), with Colorado, Massachusetts and Pennsylvania leaving them to local districts; some states also use end-of-course or exit exams.

Example: University of California (example of state-specific rules)

  • At least 15 year-long 'A-G' courses in grades 9–12 with a C or better, 11 of them finished before senior year.
  • Minimum GPA in A-G courses taken in grades 10–11: 3.0 for California residents, 3.4 for nonresidents.
  • SAT and ACT scores are not considered for admission or scholarships.

Other states' public universities set different course lists and minimums. Check your state university system and your school counselor. Source: University of California · NCES state credit table

Common mistakes in high school

  • Avoiding hard classes to protect GPA. Strength of curriculum mattered considerably to 63.8% of colleges in NACAC's survey. Challenge yourself where you can still earn good grades.
  • Treating one test as everything. Grades in college-prep courses (76.8%) far outweigh test scores (4.9%) on average — but check the colleges you want, because some require tests.
  • Applying Early Decision without checking money. ED is binding, so you cannot compare financial aid offers.
  • Assuming one state's rules apply everywhere. Required courses and minimum GPAs differ by state and by university system.
  • Missing aid deadlines. The FAFSA opens by October 1 of senior year, and many states and colleges have earlier deadlines than the federal one.
Good to know

Frequently asked questions

No. States and local districts set diploma requirements. Some states use end-of-course or exit exams, but there is no single national graduation exam.
Neither is better; schools report GPA differently. Many colleges recalculate GPAs using core subjects and adjust or remove extra weighting so applicants from different schools can be compared.
Take the most challenging courses you can handle well. Strength of curriculum matters to many colleges, but grades in those courses matter even more. Availability depends on your school, and each college sets its own credit policy.
It depends on the college. In NACAC's Fall 2023 survey, 4.9% of colleges gave test scores considerable importance, compared with 76.8% for grades in college-prep courses, but some selective colleges require tests.
Grade 9, because your GPA and course choices start counting then. Testing, college research and visits usually happen in grade 11, and applications in the fall of grade 12.
