Calculate grade

 
 
Reply Wed 2 Mar, 2011 08:32 am
Need help calculating current grade. Here's the percentages assigned:
class participation 10%
Assignments 20%
Mid-term 35%
Final 35%

The grade is based on a weighted average using the above percentage breakdowns. If I have the following grades thus far, what is my grade?

Assignment 1 7 of 10 points
assignment 2 8 of 10 points
assignment 3 6.5 of 10 points
Mid-term 68 of 100 points.

Thanks for the help.

@clemson131746,
1) Take the average of the assignments.
2) Multiply by 20%
3) Multiply mid-term by 35% and add to above
4) Divide sum by 55% since you don't know the final grade or the class participation grade.

@clemson131746,
You'll have a 86.9 but that rounds up to an 87 so thats a B.

No, the assignment average is 71.7%, the mid is 68%. The mid is worth almost twice as much so the grade so far is 69. something%, a D where I come from. Assuming that the student is coming to class the 10% participation grade will make this a C.

Do they really round up in the schools now? The correct way to do that is to start at 100% and go down, once the grade passes a divide it is no longer the higher grade, it is the lower. When I was in school teachers would hand out the higher grade sometimes, but it was always understood that the student had not earned it.

Edit: my kids tell me that some teachers still grade on a curve, which was once a common practice. If this teacher does then the grade can not be known.

@clemson131746,
Class participation and final aren't in the picture right now so I'll just go by assignments and midterm

Out of 55 potential points (20+35) you have 38 [(7+8+6.5)/30*20+68/100*35] . So your present grade is a 69%

If your attendance is perfect and you participate in class (all 10 participation points) you have 48 points out of 65, or a 74% average.
