First, you need to calculate your grade in percentages. The total answers count 21 - it's 100%, so we to get a 1% value, divide 21 by 100 to get 0.21. Next, calculate the percentage of 19: divide 19 by 1% value (0.21), and you get 90.48% - it's your percentage grade.

What are letter grades and how do they convert into percentages? Common examples of grade conversion are: A+ (97–100), A (93–96), A- (90–92), B+ (87–89), B (83–86), B- (80–82), C+ (77–79), C (73–76), C- (70–72), D+ (67–69), D (65–66), D- (below 65).

Most high school students know that a D in an academic class is a passing grade. That means they get 5 credits towards high school graduation and the course has satisfied the particular category (English, math, etc.).

It typically means you got 14 points out of a possible 20 points. If you want to convert that to a percentage, 14 out of 20 is the same as 7 out of 10, or, the same as 70 out of a 100… which is 70%. Depending upon your grading system, that is either a higher D or a lower C, etc.

Since I work in percentages, I did the math: It's the equivalent of 70%. It means that you got 70% of the answers correct, and 30% wrong. It's not bad, but it's not good, either.

First, you need to calculate your grade in percentages. The total answers count 15 - it's 100%, so we to get a 1% value, divide 15 by 100 to get 0.15. Next, calculate the percentage of 3: divide 3 by 1% value (0.15), and you get 20.00% - it's your percentage grade. Last is to get your letter grade.

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.

For example, in my own classes where I currently teach: 98–100 was an “A+”, 93–97 was an “A,” and 90–92 was an “A-”, but my colleague across the hall does 99–100 is an “A+”, 94–98 is an “A,” and 92–93 is an “A-,” with 90–91 being 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 letter grade of a D is technically considered passing because it not a failure. A D is any percentage between 60-69%, whereas a failure occurs below 60%.

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. C is anywhere between 70% and 79%

Grades of D+ through D- are passing but unsatisfactory grades. Grades of E, ABS (Absent), FL (Fail), UNS (Unsatisfactory), and EXL (Excluded) are failing grades.

According to numerous sources, colleges stopped using E as part of the grading scale because of concern over students thinking that the letter grade stood for excellent. The letter was removed despite F standing for failing or failure—and it has remained that way in the time since.

Some schools only grade with letters A-E (or A-D plus F), and among those that use percentage cutoffs for letter grades (not all of them), 10%-per-grade is most common, so a 91% is an A. An A is a 4.0/4.0. Other schools use +/- distinctions, and so an 91 would be an A-, a 3.7/4.0 or maybe a a 3.66/4.0 or 3.67/4.0.

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.

Generally, a 90-100 is considered an A or A+ (4.0) in the US. However, some schools may have slightly different grading scales, such as a 93-100 being an A. If your school uses a 90-100 scale for an A, then an average of 95 would be equivalent to a 4.0 GPA.
