EXTRA CREDIT: TEST CORRECTIONS

Students must follow this exact format to be eligible for earning points back:

For each exercise that was partially/completely wrong:

1) Write out the entire question.

2) Complete the exercise correctly with ample work.

3) Provide a brief reason as to why it was marked off the first time.

This should all be done neatly on loose leaf, stapled to the back of the test, and turned into the appropriate math bin within 3 days of class return (along with a student correction card).
