This is a sample exam.
The actual exam will be similar in structure.
1. Look through the exam before you begin.
2. The exam consists of 5 problems of varying difficulty. There is an extra
credit problem worth
6 points.
3. Show all work if you expect to receive partial credit.
4. Simplify. Give a decimal answer only after simplification.
5. NO SHARING CALCULATORS . Also keep out of sight all electronic devices except
your calculator.
That means no cell phones and no headphones.
6. Turn in scratch paper but make sure your work to be graded is on the exam –
this is your
responsibility.
