Here is a list of "Universal Grading Codes", which will be used in grading homework and exams. You can consult this translation guide to understand what the codes mean. It is up to you to go back and figure out where the error happened. This should be a formative learning experience for you, to think about how you'd approach the problem in the future. If the code you see isn't on here, it's unique to your problem and the grader should publish what they might mean in course files.
