AP Credits: Pros and Cons

Advanced Placement courses are the most widely recognized path to college credit in high school. We track 60,397 AP credit policies across 1,913 colleges, a subset of the 2,401 institutions on College Board's list.

Pros

  • Most consistently accepted at selective colleges
  • Weighted GPA boost at most high schools
  • Signals academic rigor to admissions committees
  • Dozens of subjects across all academic areas
  • Fee waivers available for low-income students

Cons

  • Requires full-year course commitment
  • Many selective schools require a 4 or 5 for credit
  • Not all high schools offer AP courses
  • Heavy workload can hurt other grades
  • Exam only offered once per year (May)

CLEP Credits: The $97 Lever

CLEP (College-Level Examination Program) is the most underrated way to earn college credit. No classroom required — just study and pass the exam. For eligible service members, CLEP exams are completely free.

Why CLEP Belongs in the Plan

  • No class required — study on your own schedule, take the exam when ready
  • 34 exams covering subjects from English to Business to Science
  • Available year-round at CLEP test centers or by remote proctoring (vs. AP's one chance in May)
  • Free prep through Modern States (free online courses + exam voucher)
  • No age limit — take CLEP at any age, even before high school

The Military CLEP Advantage

DANTES (Defense Activity for Non-Traditional Education Support) pays the full cost of CLEP exams for active duty service members, Guard, and Reserve. Combined with free GI Bill tuition, military families can earn a degree for nearly zero out-of-pocket cost.

Dual Enrollment: College Credits in High School

Dual enrollment lets you take actual college courses (usually at a community college) while still in high school. You earn both high school and college credit simultaneously.

Advantages

  • Often free or heavily subsidized by the state
  • Earn a college transcript, not just test scores
  • Experience actual college-level coursework
  • Can earn an associate degree by graduation

Watch Out For

  • Credits may not transfer to all 4-year schools
  • A poor grade goes on a permanent college transcript
  • Availability varies widely by state and district
  • May not carry the same admissions "signal" as AP

Which Strategy Is Right for You?

Choose AP if...

You're aiming for selective schools, want the GPA boost, and your school offers AP courses. AP is the gold standard for signaling academic rigor.

Choose CLEP if...

You want maximum flexibility and cost savings. CLEP is ideal for self-studiers, military families (free exams), homeschoolers, and anyone who wants credits without a year-long class.

Choose Dual Enrollment if...

Your state offers it for free or low cost, you want the college classroom experience, and you're confident in your ability to handle college-level work on a permanent transcript.

How to Stack All Three for Maximum Savings

The smartest approach is combining all three strategies. Here's a sample plan:

10

Sophomore Year

Take 2 AP courses (AP US History, AP English Language). Take 1 CLEP exam in a subject you're already strong in (e.g., Spanish, Psychology).

Potential credits: 9-12

11

Junior Year

Take 3 AP courses. Start dual enrollment for 1-2 courses at a community college. Take 2 more CLEP exams over winter and spring break.

Potential credits: 18-21

12

Senior Year

Take 2-3 more AP courses. Continue dual enrollment for 2-3 courses. Take CLEP exams for any remaining gen-ed requirements.

Potential credits: 15-21

S

Summer Before College

Take 3-5 CLEP exams to fill remaining gen-ed gaps. Focus on subjects like Introductory Sociology, American Government, and College Math.

Potential credits: 9-15

51-69 credits

That's nearly two years of college — before you even start.

What It Saves: $6,500-$30,000

Here's the math. Colleges charge full-time tuition by the semester, so credit lowers the bill when it finishes a whole semester (15 credits) early. A semester runs from about $6,500 at a public four-year to about $16,000 at a mid-tier private (about $433 to $1,067 a credit). Credit short of a semester still skips courses, but it doesn't lower the bill on its own.

Conservative

$6,500

One semester (15 credits) at a public four-year

Middle example

$13,000

One year (30 credits) at a public four-year

Higher-cost example

$30,000+
