If you got below a C- on the test I need a parent signature. Also, if you need to get a parent signature you may try to improve your test grade to a C- by correcting the problems you got wrong on another piece of paper. You must show your work. For each problem you got wrong, you need to write in sentences why you got the problem wrong. What was the error you made? You have until next Tuesday to make the corrections for the Chapter 2 test.
