* Course materials available in alternate format.  

 

 How to succeed in a Math class:

1.  Come to every class meeting.

2.  Arrive early, get yourself settled and be ready when class starts.  Sit where you won’t be                    distracted and take notes.

3.  Read each section before it is discussed in class.

4.  Do all the homework

5.  Do some math every day.

6.  Start preparing for exams at least one week in advance.

7.  Ask questions, especially if you don’t understand a concept.

8.  Take advantage of tutors and office hours.

9.      Study in groups and do your homework with a classmate.

 

The Gateway Math Center has free tutoring for all registered students.  Please Log In and Out so that the facility gets the funds it needs.

 

Calculators are not allowed for this class.

 

Homework is due every Wednesday.  It must be completed and turned in at the beginning of class. Please be neat and show your work for each homework problem.  Each section that is incomplete receives partial credit.  Homework that is turned in late but within one week of the due date will receive half credit.  Homework turned in after this receives no credit.  

Homework is 10% of the class grade.

 

2 Quizzes are given for each course.  They are given at the beginning of class before the lecture.  Please be on time. All students are to take the quiz on the same day.  If you miss a quiz, there is a penalty of one letter grade.  No quiz can be made up after 3 days.

Each quiz counts for 20% of the class grade for that course. 

 

The Final Exam is given at the end of each course.  All students must take the exam by the last day of class.  If a student does not receive a passing grade in a course, that student will not be allowed to continue on to the next course.  The final exam counts for 50% of the class grade for that course. 

Each course receives a separate grade.  Grades are based on the following scale.

 

                        A                                 90% - 100%

                        B                                 80% - 89%

                        C                                 70% - 79%

                        D                                 60% - 69%
Homework problems that say Odd, means do all the Odd problems.  

EOO means do Every Other Odd problem.
