But if you have more grades making up your 99%, then getting a zero on a 100-point assignment will hurt less. For example, if you've already taken four tests and have a 99 average, then getting a zero on the fifth test will leave you with an overall average of 79.2. (That's the average of 99, 99, 99, 99, and 0.)

It depends on how many points there are to date. If there were a total of 100 points total so far and you had 89 points, that would have 89%. If you got 0 out of 30 on the next assignment, you would still have 89 points but the total would now be 130 so your percentage would be 89/130 or 68%.

Well, a 0 could bring your grade down a lot or do almost nothing. It depends on how many grades make up your 90 if it is just one assignment it could hurt your grade a lot. However, if you have like 10 assignments that make up your 90, then it may do little damage and say lower your grade to a B+…

If you have two grades: one A and one F has an average of (0+4)/2 = 2. Your average would be a “C”. If you have three grades: A, A, F, your average is (4+4+0)/3= 8/3 = 2.67. A “C+”, but still a “C”.

A - is the highest grade you can receive on an assignment, and it's between 90% and 100% B - is still a pretty good grade! This is an above-average score, between 80% and 89% C - this is a grade that rests right in the middle.

You'll usually need to receive a letter grade between A and D to pass a class, often the numerical equivalent of 65 percent or higher. Receiving an F—which stands for “fail”—indicates that you did not pass the class. The cutoff to receive an F is usually 64 percent.

A failing grade is usually not the same as a zero, unless you have been told that all failing grades (Often 60 or 65% or lower) will be counted as zeros.

Children in sixth grade are typically 11 to 12 years old, while those in eighth grade are 13 and 14. As such, children in Middle School range from 11 to 14 years old.

A 3.0 GPA indicates a grade average of “B” and makes you eligible to apply to a wide range of schools, so yes! A 3.0 GPA is generally considered “good.”

If both grades are weighted the, i.e. if they both count the same, then you will have a 50 in the class. This comes from averaging the 2 grades. (100 + 0)/2 = 100/2 = 50.

An 86 is not bad at all. An 86 is considered above the national average, so definitely not a bad grade. If you're an A student, then this may be considered a “bad” grade to you, and it will also affect your GPA.

For example, if you had only taken one quiz with a grade of 73, and then your new quiz was a 0, your new grade would be the average of 73 and 0, or 36.5.

How much will a 50 affect my grade if I have a 100?

If thats grade is just a percentage, and the 50 is included in that percentage, the 50 lowers your grade. How much it lowers your grade depends upon how much that assignment/exam is weighted. For example, if there are 10 assignments, and you get 100 on nine of them and fifty on one of them, you end up with 95%.
