This grade computer is
for information purposes only. My records and computation are what will
determine your final grade. Let me know if the computer acts in a
suspicious way.
How to use: the grade
computer will give your current course average as well as tell you what
you need to get on the next exam in order to have a target course
average. You may also play with entering as many hypothetical
grades as you wish to see what effect they will have on the final grade.
You will need to
provide at least the exam 1 score in order for the computer to
work. Keep in mind that exam grades are entered on a 0-100
scale.
Example: after 2 exams
you had exam scores of 37/50 and 45/60. Enter in the first two
rows:
74 ( = 37/50 * 100)
75 ( = 45/60 * 100)
"Course average" will
tell you what grade you have based only on the elements earned so
far. The fields under it give you the grade (on a 0-100 scale) you
need on exam 3 in order to have a desired course average once exam 3 is
included in the computation. If any of those numbers is higher
than 100, the desired course average cannot be achieved. If you,
for example, now enter the number from "80 average" into the (empty)
exam 3 field and click "compute" again, the course average will be about
80% (allow for inexactness here because of rounding). You may
enter hypothetical grades for exam 3 and subsequent exams to see how it
will affect your final grade.
Note 1: the computer drops
your lowest exam score if you give it more than one exam. It also takes
this approach when it computes the grade necessary on your next exam in order
to have a target grade. Therefore, it may happen that the computer
reports you need a 0 on the next exam, say exam 3, in order to have, for
example, an overall 70 average. What this means is that on your previous
exams you have earned enough so that you have a 70 average based just on
your first two exams. Hence, even if you scored low on exam 3 the first two
exams will support an overall 70 average because exam 3 would be dropped.
Now, it would be an extremely bad idea to decide, for example, that you don't
need to take exam 3 because you already have a 70 average. Because
when exam 4 comes around and you score poorly, you won't have a possible
better grade from exam 3 to shore it up. Try entering "0" into exam
3 and see how much you will need on exam 4 to sustain a 70 average.
Note 2: the computer ignores any information after the first blank exam field (try it: if you enter just exams 1 and 3 you will see that nothing changes after you alter exam 3).
