<p>From what I can tell, I do not believe there is one Tulane grading system. What you have delineated is close to a couple of grading matrices I have seen, however, I believe it differs slightly by class and by major.</p>
<p>In general, I think it is.<br>
However, not all teachers use that. Many of my teachers graded on a curve. Some used z-score.</p>
