This program is for teachers adding up the scores on a multi-page test.  I 
write the number of points correct at the bottom of each page, then I use 
this program to add up the page totals to get the grand total for the test.
I can add a hundred tests up without ever taking my hand off the numeric key 
pad (the other hand holds the pen and turns the pages).  Decimals can be 
entered, so I can easily give a half point now and then.  The screen looks 
like this:
___________________________________________________________________________
How many pages?  3
Total possible [ENTER to get from first test, 1 to skip percent]:
Enter "999" to exit.
Page one:  23
Page two:  15
Page three:  12
          The total possible is  50
Page one:  19
Page two:  14
Page three:  12.5                                           Average so far
             The total is:  45.5 ( 91.0%)                   45.5  ( 91.0%)
Page one:  14
Page two:  7
Page three:  2
             The total is:  23   ( 46.0%)                   34.3  ( 68.5%)
Page one:  999

The "Total possible" is used to calculate percent.  You can enter the total 
if you know it, or just press enter if you want the program to get the total 
possible from your answer key, as was done in the above example.

Page totals can be negative.  The negative numbers can be used to correct 
for mistakes.  For example, suppose the number correct is first page, 15; 
second page, 15; third page, 2.  You plan to enter this as:
     Page one:  30
     Page two:                 (ENTER was pressed.)
     Page three:  2
             The total is:  32
but blow it by entering 60 for page one.  Still being somewhat capable of 
doing math, you pull it off by entering -30:
     Page one:  60
     Page two:  -30
     Page three:  2
             The total is:  32
Ah, but suppose you didn't catch your mistake, and got an erroneous total of 
62.  That will make the "Average so far" column wrong.  If you are going to 
enter the numbers in a spreadsheet anyway, it may not be worth your time 
worrying about that.  But, if you insist, you can correct the average by 
making a test total negative by the erroneous amount:
     Page one:  -62
     Page two:  
     Page three:  
             The total is:  -62

A word of caution:  Don't be looking at the Average so far all the time.  It
is easy to mistakenly write that number down, rather than the test total.
