Any assignment may be revisited and improved to show increased learning (and increase a grade).
Classroom tests may be retaken to show increased learning (and raise the grade from previous test).
Late assignments will be given full credit.
Once a quarter has ended it may still be possible to change a grade, but only with approval of the front office.
Missing assignments are automatically given a 50% score instead of a zero. Mathematically this is a more accurate assessment of a student's learning.
