Makeup Tests

There are 4 graded tests in this course. All of them count towards your grade. You will have an opportunity to redo up to 2 tests to replace a test if you are unhappy with your scores or you miss a test. Be aware that it is possible to lower your grade by taking a makeup exam. After you get a perfect score on the corresponding homework/quiz option. Your score for the second exam will count if it is higher. Your score for both exams will be averaged if the score on the second exam is lower. If you wish to take a makeup exam, redo the corresponding homework or quizzes for the unit until you have a score of 100%. If you needed a lot of help completing this requirement , you may want to hold off on the makeup exam until you get a chance to get more help from me or a tutor on the material. I want you to do well on exams so when time permits; it is good to make sure you understand everything before testing.

Pretest Requirements

It is expected that a student will have completed and scored at least 75% on prep/skills assignments for the unit and on one of the following:

  • Web Assign graded homework.
  • D2L unit quizzes
  • Paper homework (from a pdf file found in the course)

This must be done before the test.  There will be a review day during the class period before each test.  You should have most of this work done before the review day as one 2 hour review is not enough time to complete it, however on the review day you can ask questions and get help completing this requirement.  If you are doing the paper version of the work you must complete it by the end of the review day so that I have time to grade it and see that you are qualified to take the test.

If you desire to take a makeup test, you need to get a 100% in one of the 3 categories listed above.  However it will be too late to go back and get a higher grade on the skills assignment.

Class Attendance/Participation

A large portion of the class grade comes from in class  problems and  occasional in class experiment as well as prep and skills problems that need to be turned in during the next class after they are assigned.  It is vital that you attend and participate regularly so you can get the points associated with these items as well as get the learning opportunities.

Dropping the Course

If you find that you are unable to commit the time it takes to succeed in this course, please pay attention to the drop dates located at: and the school's withdrawal policies located:

Jan. 30, 2017:    Last day to drop with a 100% refund 

Feb. 6, 2017:     Last day to drop with a 50% refund and no record on your transcript

Apr. 26, 2017:   Last day to drop with a W on your transcript.

If you miss 2 or more classes or graded items in any one category* without communicating with your instructor, you will likely be dropped.  However if you know you want to drop, please take responsibility to do so rather than counting on an administrative drop.  Also, if you miss assignments or classes, please discuss the situation with your instructor.  I would like to help you stay in the course if that is possible. The best way to communicate with me other than in person is through the Desire to Learn e-mail system.

*Note that not achieving at least a 75% on a quiz (which you can get help with and do repeatedly until the due date and time) or at least 75% of the online homework is considered missing an assignment / quiz.

Extra Credit

Extra credit is earned on regular exam days when taken with the class by retaking the exam with your group for up to 10% more points.  If you have special needs that require you to take the exam outside of class other arrangements to be determined will be made for earning extra credit. You must show proof of special needs in order to have other arrangements for extra credit.

There may be up to an additional 10 points extra credit available that has not yet been determined.

Electronic Gradebook

Grades will be posted in Desire to Learn.


If you are under 18 years old, please note that this is a college class and as such you will be treated like any other college student.  If you have questions about anything related to this course, please ask me directly.  As a college teacher I only discuss grades and other personal information with the student that is involved.  If you want to share any information that you get from me with your parents you are welcome to do so, but please take the responsibility upon yourself to discuss issues that concern your progress in the course with me directly.

Study Time

This is a four credit course taught in 14 weeks.  For most college classes, you can expect to spend 2-3 hours per week outside of class for every hour in class.  It should take most students 16×4×(2 or 3)/14 = 9 to 14 hours per week of study time to be successful in this class.    Don't be afraid to ask for help!

Honors Option

An Academic Honors Option is a form of instructional agreement whereby a student can earn an Honors designation on his or her transcript by completing one or more approved enrichment assignments in a non-Honors course.  This course allows qualified students to complete Academic Honors Options.  The Academic Honors Option assignment(s) designed by faculty for this course are explained below.  If you elect to complete this work and do so successfully, your achievement will be noted on your official LCC transcript.  Please be aware that Academic Honors Options DO NOT earn Honors course credit.

Students seeking an Honors Option may complete one of the following assignment choices in addition to all other course work assigned by the instructor:
1.   One or more substantial mathematics projects assigned by the instructor.  Mathematics projects should either extend the mathematical content of the course or apply the mathematics within a new context.
2.   An extensive research paper on a topic germane to the course and approved by the section instructor.
Additional information will be posted on the Desire2Learn course site.

If you are interested in earning an honor designation on your transcript for this course, talk to me early in the semester about what additional work will be necessary in order to do so.
