<p>this semester, none except for gym class. yeah i know, gym class, with participation/skills/written exams/'student resonsibility' all being parts of the whole.</p>
<p>in my ap chem/chem/physics classes, all taught by the same teacher, grades weren't "offically" weighted but it was easy to to pass. You could even get an A, even if on all of you tests you got Cs and Ds. Tests were designed to be really hard, so if you did well on your homework, labs, and projects, you could do very well.</p>
<p>i also had the percentage system in my humanities class...but i did well on everything there so you know. ;)</p>
