<p>It all depends on the course and the teacher…</p>
<p>A lot of science or math classes will do it pure numbers… i.e. get 15% for homework, 45% tests, 40% final.</p>
<p>Some classes will have “class particpation” as a grade, which means how much you suck up to the teacher. Some classes put more weight in tests, some put more in assignments.</p>
<p>It all depends on the teacher, nothing is really standardized.</p>
