Guide to Homework Grades

I grade problems in one or more parts, depending on how many different questions or how many parts to the solution there are. For instance, often an if-and-only-if proof is graded with one grade for each direction.

How you present a solution is part of what I grade, not only whether it's technically correct. An inefficient solution is worth less, a particularly inventive or elegant solution more. I summarize the criteria as: completeness, method, and writing.

I will expect a submission on time for every part of every problem. ("On time" means "before I start grading", since sometimes the grading is delayed.)
Partial solutions are better than no solutions!
You can submit a revised solution later, or a fresh solution late (which counts as a revised solution). But not too late – say within a couple of weeks. Submitted rewrites must be accompanied by the original solution.
