How to Test Out of College Courses and Actually Save Money

Answer sheet, pencil, and clock representing testing out of a college course by exam

Picture starting sophomore year already holding 15 college credits you never sat through a single lecture for. Not because you cheated. Because you took three exams instead of three semesters, and your college let you, on paper, no questions asked.

That's the whole logic behind testing out of a course: prove you already know the material, skip the tuition-eating repeat, move on. The tools for doing this have existed since the 1960s (CLEP is older than the internet by a wide margin), yet most students never hear about them until a bored advisor mentions it in passing during junior year.

The Four Real Ways to Test Out

There are basically five doors into skipping a course, and they don't lead to the same place. Advanced Placement (AP) exams happen in high school. CLEP and DSST are exam-only options open to anyone, any age, anywhere.

Institutional challenge exams are your own college's private test. Portfolio review, sometimes called prior learning assessment (PLA), trades documentation of real-world skill for credit instead of a test at all.

Mix these up and you'll waste money on the wrong one. A working adult with fifteen years of IT experience should probably build a portfolio, not cram for a DSST in Introduction to Computing. A high schooler already fluent in Spanish should sit the AP exam, not wait around for a college challenge exam that may not even exist.

Here's how the five stack up:

Method	Typical Cost	Time Investment	Acceptance
AP Exam	About $99/exam (fee reductions available)	A full high school course, then a 2-3 hour exam	Nearly universal, but credit amount and required score swing wildly by school
CLEP	$97/exam, plus up to a $25 test-center fee	Self-paced study, often 4-8 weeks	About 2,900 colleges accept some CLEP credit
DSST	About $100/exam, plus a possible center fee	Similar to CLEP, self-paced	Roughly 1,900 colleges, heavier military and adult-learner use
Institutional Challenge Exam	Often $25-$100, sometimes a per-credit fee	Days to a few weeks of prep, one sitting only	Only at your own school, and only for courses that offer it
Portfolio/PLA Review	$100-$500+ evaluation fee	Weeks to months assembling evidence	Varies enormously; strongest at adult-serving institutions

CLEP and DSST: The Exam-Only Route

CLEP: the general-education workhorse

CLEP, run by the College Board, covers 34 subjects, mostly the classes everyone takes anyway: composition, U.S. history, macroeconomics, college algebra. According to the College Board's own CLEP data, close to 2,900 institutions grant credit for at least one exam, though the number that accepts any given exam is much smaller.

Here's the misconception that trips people up: not every school treats CLEP the same way. One university might award three credits for a 50 on College Composition; another requires a 65 and offers only placement, not credit, meaning you skip the class but still pay for those credit hours somewhere else in your schedule.

Nonprofit groups like Modern States Education Alliance will cover your CLEP exam fee entirely if you finish their free prep course first — a detail almost nobody mentions, and one that alone erases the $97 cost per test.

DSST: built for adult learners and niche subjects

DSST exams run about $100 and cover ground CLEP skips: cybersecurity, ethics in America, technical writing, some upper-level business courses. Around 1,900 schools accept DSST credit, and it's the go-to exam on military bases because Tuition Assistance often covers the fee outright.

The tradeoff: DSST's subject list leans professional and technical, so a traditional eighteen-year-old freshman usually gets more mileage out of CLEP's general-education lineup instead.

Institutional Challenge Exams: The One-Shot Option

How the one-shot rule works

Every college writes its own challenge exam policy, but most share a blunt rule: you get one attempt, period. Fail it, and you're stuck taking the regular class, no do-over, no partial credit, no bargaining with the professor.

Typical restrictions repeat across catalogs like Austin Community College's: no challenging a course you're enrolled in, none for one you've already gotten a grade in (D or F included), and a cap near 25 percent of your degree's credits total. Pass, and it posts as a CR grade that never touches your GPA.

Why almost nobody uses this

Institutional challenge exams are, in my opinion, the most underused tool on this whole list, and that's a shame. They often cost less than CLEP, they test your school's exact syllabus instead of some generic outside material, and departments rarely publicize them because filling seats pays the bills.

If you already know a subject cold, say you grew up bilingual and your college's intro Spanish sequence would be a formality, walk into the department office and ask directly whether a challenge exam exists. It's usually not listed anywhere on the website.

Portfolio Review: Turning Experience Into Credit

Portfolio assessment, or prior learning assessment, skips the exam altogether. You assemble documentation instead: work samples, certifications, training records, a written narrative, and a faculty member decides whether it matches a specific course's learning outcomes.

Here's the misconception worth killing: portfolio credit is not a reward for having a job. A paramedic with eight years of field experience doesn't get automatic credit for Anatomy and Physiology. They get credit only if the portfolio proves they mastered the course's actual outcomes, documented and specific, not just implied by a job title.

Credit is not awarded for experience; it's awarded for demonstrated, documented learning that lines up with a course's outcomes.

Limits vary by school. Some cap portfolio credit around 30 hours toward a bachelor's degree and 15 toward an associate degree; others allow it to cover up to a quarter of the entire program. Either way, expect an evaluation fee in the hundreds of dollars and weeks of writing, not a quick multiple-choice afternoon.

This route makes the most sense for adult learners returning to finish a degree with real career history behind them. An eighteen-year-old fresh out of high school almost never has enough documented prior learning to bother.

How to Check If Your School Actually Accepts It

Don't spend $97 on a CLEP exam before confirming your target school wants it. Acceptance and score requirements live entirely with the receiving institution, not with the College Board or DSST.

Three places actually have the answer:

The College Board's AP and CLEP credit-policy search tools, searchable by school name, listing required scores and credit amounts, though the listings sometimes lag behind reality.
Your registrar's transfer-credit or credit-by-exam page, usually buried three clicks deep, so search the site directly instead of trusting a Google snippet.
A direct email to the department, especially for institutional challenge exams, which rarely show up in any searchable database at all.

Get the answer in writing if you can (a saved email works fine), because advisors change jobs and verbal promises evaporate.

Watch for the placement-versus-credit trap, too. Some schools let a high AP or CLEP score exempt you from a prerequisite without granting actual transcript credit. That changes your total credit count and, at some schools, your financial aid eligibility tied to full-time status.

The Real Math: What You Save, and What You Risk

Run the numbers and testing out looks almost unfair. At the 2025-26 average in-state public tuition rate of $411 per credit hour, a standard 3-credit course costs $1,233. A CLEP exam covering the same material costs $97 — cutting the price of that credit by about 92 percent.

Stack four exams across a degree (say, composition, macroeconomics, U.S. history, and college algebra) and you've swapped 12 credit hours of tuition, worth $4,932 at that same rate, for around $400 in exam fees and a summer of studying. That's not a rounding error. That's a semester's rent, gone, saved.

But the math has a catch. Credit-by-exam usually posts as pass/fail or "CR" on the transcript, so it does nothing for your GPA. Fine if you'd have earned a C in the class, a real loss if you needed an A to keep a scholarship tied to grade minimums.

Some financial aid packages also require a minimum number of credits taken in residence, so testing out too aggressively can shrink your eligible aid instead of your bill.

Transfer isn't guaranteed either. A CLEP score your current school honors might mean nothing if you transfer later, since the receiving school sets its own cutoff independent of whatever you were promised the first time around.

Step-by-Step: Actually Doing This

Here's the sequence, in order:

Pick a course you're honestly confident you could pass without attending. Overestimating here wastes the exam fee and, for challenge exams, burns your one shot.
Check your target school's specific policy using the registrar page or the College Board's search tool before spending a dollar.
Confirm the score cutoff and credit amount in writing, and ask directly whether it's credit or just placement.
Pick the right mechanism: AP in high school, CLEP or DSST for general self-study, institutional challenge for a course specific to that school, portfolio for real documented work history.
Study on an actual schedule, even for material you feel ready on. Modern States' free courses exist for exactly this if you're going the CLEP route.
Take the exam, send the official score report straight to the school, then follow up with the registrar in writing once it posts.

Skip the order and you risk the exact scenario that gives this whole idea a bad reputation: a wasted fee, a burned attempt, or credit that never actually lands on the transcript.

Bottom Line

Match the mechanism to your situation: AP in high school, CLEP or DSST for broad self-study, institutional challenge for one specific course at your own school, portfolio for adults with documented work history.
Verify acceptance before spending anything, using the College Board's search tools and your registrar's page, not word of mouth from a classmate.
Remember credit-by-exam rarely helps your GPA, so think twice before testing out of a class where you'd have earned an A and needed it.
Institutional challenge exams are underused and worth asking about directly, even when a department doesn't advertise them anywhere.
If the math works, and for most general-education requirements it does, the savings are real money, not a gimmick.

Frequently Asked Questions

Does every college accept CLEP credit the same way?

No. About 2,900 schools accept some CLEP credit, but each sets its own required score and credit amount, so a passing score at one school might earn nothing at another.

How do I find out if my school accepts a specific exam?

Search your school's registrar or transfer-credit page directly, cross-check it against the College Board's AP and CLEP credit-policy search tool, then email the department for anything not listed publicly, especially institutional challenge exams.

Can I retake a challenge exam if I fail it?

Almost never. Most institutional challenge exam policies allow exactly one attempt per course, so failing means registering for the regular class with no second try.

Does testing out hurt my GPA?

It can't hurt it directly, since most credit-by-exam posts as pass/fail or CR on the transcript, but it can't help it either, which makes it a poor choice for a class where you needed the grade boost.

Is portfolio review only for people with prior college experience?

No, but it works best for adults with documented work history, military training, or professional certifications, since portfolio credit is awarded for demonstrated learning outcomes rather than years on a job.

Will credit-by-exam transfer if I switch schools later?

Sometimes, but the new school evaluates it under its own policy rather than the one you originally earned it under, so a transfer can mean redoing the whole verification step from scratch.
