Bonuses and Penalties in Grade Books
 

Hi all,

I am working on an assignment in my textbookwith a grade book. I've
already figured out the test average of 3 tests using the SUM and MIN
functions. The test grades are in cells B4:E4. I had to drop the
lowest grade and compute the average of the remaining three, which I've
already done.
=SUM(B4:E4)-MIN(b4:E4))/3
There is a next part I am stuck on. Students are required to complete a
designated number of homework assignments(which is 12 and it is in cell
E19). Then receive a bonus or penalty for ever additional or deficient
home assignment. The bonus is added to the test average to determine
the semester average. The penalty for each assignment missing is 2 and
that info is in cell E20 and the bonus for each additional assignment
is 1 and that info is in cell E21. Cell H4 is the bonus or penalty and
I4 is the semester average.
I would be grateful for any help. Thanks!

Kahlan

Oh, the number of homeworks is in G4 and bonus or the bonus or penalty
formula will go in H4.

Thanks,

Try this single formula, which will calculate the semester average by just
using the number of homework assignments completed that were entered in G4.

No need for a separate bonus or penalty calculation cell, unless you might
want it for reference.

Enter this in I4:

=AVERAGE(LARGE(B4:E4,{1,2,3}))+(G4<12)*((G4-12)*2)+(G412)*(G4-12)

Try this:

In Cell E20: * =if(G4<12,(G4-E19)*2,"")*

In Cell E21: *=if(G4=12,G4-E19,"")*

In Cell H4: *=if(E20="",E21,E20)*


Therefore, the semester average in Cell I4:

=((SUM(B4:E4)-MIN(B4:E4))/3) + H4


I hope this is what you need.

Regards.
