In most colleges, earning below a 60% in a course results in an F, which is the universal failing letter grade. But “failing” in college goes beyond a single bad grade. A D in a major course, a cumulative GPA below 2.0, or not completing enough credits per semester can all function as failing, depending on the context. Understanding where each threshold sits helps you know when you’re actually in trouble and when you still have room to recover.
The F Grade and Where the Line Falls
The most straightforward definition of failing is receiving an F on your transcript. At the vast majority of colleges, an F corresponds to a course average below 60%. Some schools set the cutoff slightly higher, at 62% or 63%, but 60% is the most common threshold. An F earns zero grade points, which means it drags your GPA down without giving you any credit toward graduation.
A D grade (typically 60% to 69%) is technically passing at many schools, meaning you earn credit hours for the course. But that distinction matters less than you might think, because a D often fails to satisfy the actual requirements you need it for.
When a D Counts as Failing
Most colleges require at least a C or C- in courses that count toward your major, minor, or concentration. At Northwestern University, for example, courses with a D grade cannot fulfill major, concentration, certificate, or minor requirements. This policy is common across schools nationwide. So if you earn a D in organic chemistry and you’re a biology major, you’ll likely need to retake it even though it’s not technically an F.
Prerequisites work the same way. If a course requires a C or better in the prior class, a D means you can’t move forward. In practice, earning a D in a core course creates the same outcome as an F: you retake the class, spend additional time and tuition, and fall behind in your degree sequence.
GPA Thresholds That Trigger Consequences
Your cumulative GPA is where individual grades compound into institutional consequences. Most colleges require a minimum 2.0 cumulative GPA (a C average) to remain in good academic standing. Dropping below that line typically triggers academic probation, a formal warning that you’re at risk of being unable to continue.
Academic probation usually lasts one or two semesters. During that time, you keep taking classes, but you may face restrictions like reduced course loads or mandatory advising appointments. The probation itself isn’t the end of the road. What matters is what happens next. If your GPA doesn’t improve, the school can escalate to academic suspension, which means you’re barred from enrolling for a set period, often one or two semesters. Students who return from suspension and still can’t raise their grades face academic dismissal, which is permanent removal from the institution.
Some programs within a university set their own, higher bar. A nursing or engineering program might require a 2.5 or even a 2.75 to stay enrolled in the major. Falling below that threshold can get you removed from the program even if the university itself would keep you enrolled as a general student.
How Failing Affects Financial Aid
Federal financial aid requires you to maintain satisfactory academic progress, commonly called SAP. Each school sets its own SAP policy, but the standards generally include three components: a minimum cumulative GPA (usually 2.0), a completion rate (you must pass a certain percentage of the credits you attempt, often 67%), and a maximum time frame to finish your degree (typically 150% of the published program length, so six years for a four-year degree).
Failing a course hurts you on two of those fronts. The F lowers your GPA and counts as attempted but not completed credits, which damages your completion rate. If you fall below your school’s SAP standards, your federal grants and loans can be suspended. Most schools allow you to file an appeal if there were extenuating circumstances, but the burden is on you to demonstrate what went wrong and how you’ll fix it.
Retaking a Failed Course
Most colleges allow you to retake a course you’ve failed, and many offer some form of grade replacement for undergraduates. Under a typical grade replacement policy, only the highest grade earned appears in your GPA calculation, even though both attempts stay on your transcript. At the University of Arizona, for instance, when an undergraduate repeats a course, the GPA reflects only the highest grade. This means a strong second attempt can effectively erase the GPA damage from the F.
There are limits to be aware of. Many schools cap the number of courses eligible for grade replacement, sometimes at three or four over your entire undergraduate career. Graduate students generally don’t get the same benefit. In graduate programs, all attempts typically count in the GPA, so retaking a failed course helps, but the original F still weighs on your average.
Even with grade replacement, the original F remains visible on your official transcript. Graduate school admissions committees and some competitive undergraduate programs will see every attempt. A retaken course with an improved grade tells a recovery story, but the initial failure doesn’t disappear from the record entirely.
Withdrawal vs. Failure
If you’re heading toward a failing grade and catch it early enough, withdrawing from the course is usually a better outcome. A W (withdrawal) appears on your transcript but carries no grade points, so it doesn’t lower your GPA. Every school sets a withdrawal deadline, typically several weeks into the semester, after which you’re locked into whatever grade you earn.
Withdrawals aren’t free of consequences, though. The course still counts as attempted credits for financial aid purposes, which can hurt your completion rate. And a transcript with multiple W’s can raise questions for future programs or employers. Still, a W is almost always preferable to an F when the math on passing no longer works out.
What “Failing Out” Actually Means
People often use “failing out” loosely, but the formal process has distinct stages. A single failed course doesn’t get you expelled. It takes a pattern of poor performance, reflected in a cumulative GPA below the school’s minimum, sustained over multiple semesters despite being placed on probation. The typical sequence is: probation after one bad semester, suspension if the next semester doesn’t improve, and dismissal if a return from suspension still doesn’t produce adequate grades.
The timeline varies by institution. Some schools move from probation to suspension after a single semester without improvement. Others give students two or even three probationary semesters before escalating. If you’re placed on probation, the specific terms will be spelled out in a letter or advising meeting, including exactly what GPA you need to hit and by when. That’s the number that matters most at that point, not the grade in any single class.
