Not a teacher of course. Here's how I graded though.

With student #1, I calculated he had a total percentage of 56% of all points possible. Unless grading occurs on the curve, he fails the class. I suppose some might say he qualifies for a D-. This is simple. I just used numerical averages.

With student #2, some assumptions have to be made. I assumed as follows:

A 'B' is equal to 80%

A 'D' is equal to 60%

An 'A' is equal to 100%

An 'E' is equal to 0% (most questionable assumption I made, but I have no numerical data to know whether the student got 50% or 0% possible).

Finally, a 'C' is equal to 70%.

Following these rules, I gave the student 56% total. The student either fails the class or he gets a D-.

Do I get to be a teacher or not?

There may be more factors involved than the numbers.

==>What grade level are you teaching?
==>Do you, or does your school, have a policy allowing you discretion for circumstances beyond the student's control or allowing for makeups?
==>Is there evidence that the two consecutive scores of 0% and 25% were due to illness or some other emergency?
==>Is there some basis, like the entire class did astoundingly badly, for you to think that it would be fair to throw out the 0% or 25% scores?

Good luck.

Not a teacher either, but work in education.

Student 1 and Student 2 both get Ds. This is assuming E is 0%.

Student 1's grade is mathematically higher even if I gave Student 2 high percentages.

Now if the 'E' grade is considered failing but just under 50%, then Student 2 would have a low C.

There would also be the implicit and non-mathematical grade of effort.

If the percentages and grades are listed in a linear fashion then it looks as though Student 1 is improving and Student 2 is kind of bouncing around.

Also other factors would come into play, but strictly mathematically speaking it looks as though it's highly dependent on how you define your percentages.

63%, 0%, 25% 74%, 83%, 93%, 74%

If there are no other considerations like participation, effort, or an IEP The true average is 59% and if there is no problems and the student gave it their best I might give them a passing grade.
I would need to know how they earned a ZERO and wonder why they have a 25%?

Student #2 scores as follows

B, D, A, E, C, E, C

Average is around a C-?
Same parameters would get the student a C in my class.
I would look at why there are extremes in the grades they earned. Were the conditions different when they earned the A and / or the E's?

If they are slackers, #1 fails and #2 has a C-...eactly what they have earned..

I'm curious what an E means...? I guess that's below an F, so a 0%?

I assume all assignments are weighted the same (aka one grade isn't a test grade and the other isn't a homework grade)

Student 1: 58.85% - F
Student 2: I guess I'd do a +/- system, so B- would be 80%, B would be 84%, B+ would be 88% or there about, so I'd say 55.71%, also an F

I don't really believe in the "A for effort" mentality. If a student can't get good grades they either need to study harder/take academics more seriously, get tutoring, or in cases where they really cannot do the work, be put into remedial programs.

Student 1 looks like they were at least trying except for the 2nd and 3rd grades. I would need to know what was going on at that time to cause that rough patch. Depending on the answer, I would consider dropping the 0 and averaging on the rest, which would allow them to pass the class.

I don't know what an E is, so I can't comment on the second one.

For the first student, 58%.
For the second student, unknown. The "Es" could represent any number from 0 to 59.999999 (repeating).

The other problem is that even if the Es were a known factor, the scores for the second student would still be in a range varying by ~10% for every other score besides the Es -- that is, a B could be anywhere from 80% to 89%, and so on.

That's why I sincerely wish we would give percentages instead of letters. A kid who has gotten a 79% is getting a C, but s/he's worked 9% harder (or at least, done 9% better) than one receiving the same C with a grade of 70%.

74% which is the median & the mode. The mean is too distorted by the 0%.

Actually, student 2 has the letter grades associated with the percentages student one has. You make my point beautifully though.

It was suggested, in another thread, that an E be given a score fo 50%. Converting to letter grades before averaging has the same effect. You just failed student one on the same grades you passed student 2.
