Grade Computer
Check the appropriate button and enter all the fields up to at least Exam 1.  Exam scores are to be entered on a 0-100 scale:

Course average: %


For better than overall course average you need at least this grade on the next exam
90 average %
80 average %
70 average %
60 average %

The grade computer will give your current course average as well as 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.

Example on how to use: you have homework scores of 45, 31 and 52 (out of 50, 42 and 56), and you have two exam scores of 31 and 34 (out of 35 and 39).  Enter in the first two rows:

128 and 148 (45+31+52 and 50+42+56)
88.57 and 87.18 (31/35 and 35/39 scaled to 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 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 exams 3 and further to explore what happens to the final grade.

Note 1: You will need to provide all the fields up to at least exam 1 in order for the computer to work. 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).

Note 2: if you enter three exam grades, the computer may report you need 0 points on the next exam (final) to have a particular grade, say 70. Since the final exam only replaces your two weakest exam grades, if your grades before the final already support 70, then you don't need any points on the final exam to make a 70 overall.

Note 3: the computer assumes that non-exam scores are always 40% of the grade.
