How much does one zero lower my grade?

It depends on weight and how much other work counts. One zero out of ten equal assignments turns a 90% into an 81%. Earlier in the term it hurts more.

Can I recover from a zero?

Usually yes, but you need more points than the zero cost, because you’re averaging against a larger total. Enter your remaining work to see the average you need.

Does a zero count the same as missing work?

A recorded zero counts against you. “Not graded yet” is left out until scored — that’s why your grade can drop when a zero is entered.

How much does a zero affect your grade?

A single zero can drop your grade more than you expect. How much depends on the assignment’s weight and how much other work counts. See the math and how to recover.

One zero’s impact depends on its weightand how much other work counts.Early in the term, a zero hurts most — here’s the math.

A zero hurts because it adds possible points with nothing earned. How much it moves your grade depends on two things: how heavily that assignment is weighted, and how much other graded work it is averaged against.

Points courses: it’s about the denominator

In a points-based course, a zero adds the assignment’s possible points to the denominator and nothing to the top. The fewer other points exist, the bigger the drop.

One zero out of ten

Say you have 90% across nine equal 100-point assignments: 810 out of 900. A tenth assignment scored 0 out of 100 makes it 810 out of 1,000 = 81%. One zero turned a 90% into an 81% — a nine-point drop. Earlier in the term, with fewer points banked, the same zero would hurt even more.

Weighted courses: it’s about the category weight

In a weighted course, a zero only moves the category it sits in, then that category moves your grade by its weight. A zero on a quiz in a 10%-weighted quiz category matters far less than a zero on a 30%-weighted project.

Can you recover?

Yes, but it takes more points than the zero cost, because you’re now averaging against a bigger denominator. Enter your remaining work and a target in the points grade calculator to see the average you’d need. The raise-your-grade guide covers the recovery math.

Zero vs missing vs ungraded

A recorded zero counts against you now. Work that is simply not graded yet is left out until it’s scored — so your running grade can drop sharply the day a zero posts.
