For finals, how do you see how low of a grade you can get on a final on a calculator (see details please)?

Question

I think all my finals are 20% of the total grade, so I guess the rest is 80% of everything. How could I see the lowest I could get to keep my grade AND how could I see the highest grade possible? Thanks

Answer 1

1. add up all the points possible for the class
2. add up the points you earned
3. Divide the points earned by the points possible... that is your percentage/ grade!

Answer 2

Suppose your goal is a 90% overall and you currently have 95%.

Total grade = (80% * current grade) + (20% * X).
X= grade on finals
Substitute your desired total grade in and current grade and solve for X:
90= 0.80 * 95 + 0.20 X
X=70

You can substitute another current or desired total grade.

--------
Your best possible grade is (0.80 * current grade) + (0.20 * 100 on the finals)

Answer 3

Grab a calculator, Get your other two grades, and add them twice... Example:

81+81+85+85

Then on the last one add your semester final. Example:

81+81+85+85+91=423

So then divide 423 by 5...

And your average is 84.6%. There you go!
