Examination/test Grading Policies

The tests and the final exam also have extra credit questions. Most questions (if not all) are multiple choice type with 5 choices. Each test/exam has a base number of questions and a total number of questions. The total is always larger than or equal to the base. Let $r$ be the score from correct answers, $b$ be the base number of questions and $t$ be the total number of questions. The break points of letter grades are as follows:

• F if $\frac{r}{b} < \frac{0.1 \times b+0.2 \times t}{b}$
• D if $\frac{r}{b} < \frac{0.3 \times b+0.2 \times t}{b}$
• C if $\frac{r}{b} < \frac{0.5 \times b+0.2 \times t}{b}$
• B if $\frac{r}{b} < \frac{0.7 \times b+0.2 \times t}{b}$
• A if $\frac{r}{b} \ge \frac{0.7 \times b+0.2 \times t}{b}$

The break points for the letter final grade are weighted averages of the components from the homework assignment component and the exam components.

I reserve the rights to change the grading scheme throughout the semester. I will make the changes public to the entire class whenever changes are made.

In order to receive your grade, you should sign up for a ZIP account if you have not done so already. You must sign up at on-campus, although you can access your account via the internet once you have an account. Visit http://zip.arc.losrios.edu to sign up for an account. Your midterm grade and final grade are both sent to this account. I will also send emails to your ZIP accounts regarding course materials and homework assignments.
