AP Credits: Pros and Cons

Pros
- Highest acceptance rate of any credit-by-exam option
- Weighted GPA boost at most high schools
- Signals academic rigor to admissions committees
- 38 subjects available 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 $90 Hack
CLEP (College-Level Examination Program) is the most underrated way to earn college credit. No classroom required — just study and pass the exam. For military families, CLEP exams are completely free.
Why CLEP Is the Best Kept Secret
- 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 Prometric test centers (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 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:
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
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: 15-21
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
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
48-69 credits
That's nearly two years of college — before you even start.
Average Savings: $20,000-$40,000
Here's the math. Each college credit costs between $350 (public in-state) and $1,500+ (private). Every credit you earn through AP, CLEP, or dual enrollment is a credit you don't pay full tuition for.
