Math 131		Assignment 29		due 9 AM 6 Apr.

	The group quiz on Wed. is on sec. 4.5.

	If your score on test 3 was above 25, then to improve your score 
	on test 3, you can correct each problem for which you did not 
	earn 6 points.  You must make the corrections on separate paper 
	from the original test.  You must submit the test and the corrections.
	Your score on test 3 will be the average of the original score and 
	the corrections.  You should be able to earn full credit on the 
	corrections if you apply yourself.  The corrections are also due 
	on Fri. 8 Apr.

	If your score was below 25, then you should make test corrections
	as usual but the average rule does not apply for you.  To improve
	your score, you should take a retest.  The retest will be similar
	to the original test and will fully replace your original score 
	on test 3.   The retest will be Fri. 8 Apr at 2 or 330 PM, depending
	on whether or not I have a 2 PM meeting.
