### COURSE MATERIALS

Math 125 requires a custom textbook with a MyMathLab Access Code. The required textbook is *Math 125* 2nd custom edition for UIC, available in our bookstore only.
Optional to the student is to just purchase access to MyMathLab.

Regardless of the option chosen by the student, MyMathLab Access is required, grades will not be given to students without full semester access activation.

We will cover chapters 1 - 4 and 8 - 9. A brief description of the material covered each week is given in the weekly schedule below. You are expected to read the textbook before the classroom discussion of each topic, as indicated on the schedule of homework and reading assignments.

A graphing **calculator** such as TI-83, TI-83+, TI-84 or TI-84+ is **REQUIRED** .
You may use it on exams, however, you will still be required to show work in most cases.

### PREREQUISITES

MATH 090 or a grade of C or better in MATH 121 or appropriate performance on the UIC mathematics placement test.

### GRADING

The course grade will be determined by Midterms, Quizzes, Homework Assignments, and the Final Exam shown in the table below. The grading scale of 90%(540 pts) for an A, 80%(480 pts) for a B, 70%(420 pts) for a C, and 60%(360 pts) for a D are guaranteed levels for each letter grade.

Two Hour Exams | 100 points each |

Quizzes(best 6 of 8) | 120 points total |

Homework | 80 points total |

Final Exam | 200 points |

Total | 600 points |

### QUIZZES

QUIZZES: The policy on quizzes is that we are dropping the lowest 2, and so using the best 6 of 8. Due to this there are NO MAKE-UPS on quizzes. Missed quizzes count as Zero and will be dropped if the student misses no more than two.

### EXAMS

There are two Midterm Exams, to be given at 6:00-7:30pm, ALL lectures at once, on the following dates

Monday, October 9th

Monday, November 13th
