Overview

Extra-Credit work is due by the specified deadline per quarter and is averaged as a percentage grade with Quiz/Review.  You are given an opportunity for extra-credit to serve as enrichment for concepts taught in class.  However, the grades do affect your overall average and may be useful if you had done poorly on a particular assignment.

The maximum of 10 points may be earned, unless you choose an individual project that is worth more than that.  In the case of a higher point project, you can earn the maximum of the total points of that project.

4th quarter extra credit should be started earlier in the year to provide enough time to complete the tasks.

This is calculated by multiplying the total number of extra-credit points by the total of Quiz/Review Assignments for that quarter.  In the 1st Quarter the max is 10 points times 8 quiz/reviews or 80 points.
