Each problem needs to be 100% correct before receiving credit. That means you need to have 100% correct work with the correct answer. You can receive up to a maximum of 50% of the points you lost on your test. To receive credit, I must have your original test or it will not be accepted. You do not need to do problems you already got correct on your test. You are welcome to work on the extra credit problem as well.
