Your 4th set of Window panes won't be due until Wednesday! You get an extra Day. Why?
Because for the rest of the semester your window panes will be handled like a project. If you have been doing them correctly, you know how long it takes and will agree that they deserve to have more weight than a homework grade. I've decided that I will add them all together at the end of each grading period( not including the ones you have already done) and grade them as a project, just like the book you will be writing shortly!
