<p>If you know and can communicate/evaluate 100% of the material, you have earned a 100% as a grade. If you know and communicate/evaluate 70%, that is the grade you should recieve.</p>
<p>Amount of effort and entitlement should not be a significant aspect of a grade. Mastery of the material and communication of such is the goal in most places.</p>
<p>I disagree with anyone setting a “default grade.” You should be graded on your performance, and classes should be taught at a suitable level for how well the average student can perform (i.e. don’t teach Calc II to 3rd graders).</p>
