How to Contact Me:
I am here to help you succeed in this course. Although we will interact regularly on your assignments and exams, occasional questions or problems may arise. Here's how to contact me when they do.

If you need to meet in person, please contact me for an appointment during my office hours:

Your Email Account:
You have been assigned a VCCS email address for use in this and other courses that you take through NVCC or other colleges in the Virginia Community College System (VCCS). The VCCS requires that you use this email account for any course-related email communication so that we can insure your privacy as required by law. If you don't know your VCCS email address, go to the Start Page and search for your address.

To log on to your email account and check for mail, click the Student Email tab near the top of this page. Enter your complete email address as your user name. Use the same password as you first used to log onto Blackboard (either the birth date you gave when you registered, or the last 4 digits of your student number). If you need help using the email account, go to the Email Login Page and click the link to "online documentation".

Please check your email regularly. That is how I will inform you of grades, approaching due dates, or other private, course-related information. I will also reply to your emails at your VCCS account. I will not accept or respond to email sent by you from any account other than the one provided by the VCCS.

Discussion Forums:
In addition to email, you, I, and the other students in the course will communicate using discussion forums. Discussion forums allow you to post your ideas and comments and read and respond to the ideas and comments of others, without having to be connected to the course at the same time.

To access the discussion forums click the DISCUSSION BOARD button. At this point you will be presented with a list of all the discussion forums. Click on the forum that you wish to access. Click the ADD NEW THREAD button at the top of the page to create a new message. You can also click the subject of any message to read it, or click the REPLY button to write a response to a message.

There is an Introductions Forum, where we introduce ourselves, and an Open Forum, where you can ask questions or post comments about anything in the course.

Course Summary :

MTH 166 is a unified course in precalculus with trigonometry designed to prepare you to take MTH 173 (calculus for students in mathematics, engineering, or computer science). The prerequisite is three units of high school mathematics, and a placement exam is given to be sure that your math skills are adequate to enroll in MTH 166 . Credit cannot be awarded for both MTH 163 and MTH 166 .

Course Progress:

ELI is designed for students with busy and sometimes irregular schedules. Most ELI courses do not require fixed assignment due dates. However, research shows that students are most successful with independent study when they start their course work on time and make steady progress. To help you do this, we suggest that you try to follow the timeline below. Base the months on your specific enrollment dates.

Month 1

Chapter P, Sections 1, 2, 3, 4, 5

Quiz 1

Chapter 1, Sections 1, 2, 3, 4, 6, 7

Quiz 2

Review, take Exam 1



Month 2

Chapter 2, Sections 1, 2, 3, 4, 5

Quiz 3

Chapter 3, Sections 1, 2, 3, 4, 5, 6

Quiz 4

Review, take Exam 2


Your Last Withdrawal Date falls approximately 9 weeks after your enrollment begins.

Month 3

Chapter 4, Sections 1, 2, 3, 4, 5

Quiz 5

Chapter 5, Sections 1, 2, 3, 4, 5, 6, 7

Quiz 6

Complete Course Evaluation

Your End of Enrollment Date falls approximately 4 months after your enrollment begins. By this date, you should have completed all work for the course. If you have not, but you have satisfactorily completed approximately 75% of the course work, you may request a grade of Incomplete (I). See the section on Incomplete Grades for more information.




























Course Evaluation:

Please take time to complete the Course Evaluation survey at the end of your course. This is a short, online survey that provides valuable feedback to ELI and its instructors. You will have an opportunity to complete the survey when you go to the Testing Center for your final exam. Or, if you have a computer with Internet access, you can complete the survey online anytime.

Grading Scale :

The course grading criteria are listed below:

Possible Points
% of Final Grade
4 Exams
8 Quizzes

Before you take any exam, two quizzes are due to your instructor. These quizzes are designed to prepare you for the exams.

Final grades will be based on the following scale:

A = 90100% = 432 to 480 points

B = 8089% = 384 to 431 points

C = 7079% = 336 to 383 points

D = 6069% = 288 to 335 points

F = Below 60% = Fewer than 288 points

NOTE: For MTH 166, you must submit all quizzes and take all four exams in order to pass this course, regardless of how well you do on the other assignments. Please keep a personal record of all your grades so that you can compute your own course grade.

Withdrawal from this course
You may withdraw yourself from this course at any time until your Last Withdrawal Date. You must withdraw before the Last Refund Date to receive a refund. For your specific course dates, refer to the Quick Start Syllabus mailed to you by ELI. For additional information, see Enrollment Dates and Withdrawal Policy.

I will withdraw you from the course if you have not shown progress at key checkpoints during your enrollment. You must have met the requirements listed below to stay in the course:

Inactive Students Dropped
You must submit at least one graded assignment before this date or I will withdraw you from the course without refund.

Last Withdrawal Date
You must submit at least 50% of the course before this date or I will withdraw you from the course without refund.

The incomplete grade is used for verifiable unavoidable reasons.  If you have made significant progress in your course, your end date is near, and you have reasons that can be documented as unavoidable, you may request a grade of Incomplete.  To request a grade of Incomplete for this course, you must:

  • Have satisfactorily completed 75% of the course.
  • Explain your extenuating circumstances to me in writing.

ELI Policy and Proceedure:

The ELI Web Site will answer many general questions about ELI and the courses available through ELI. Please also read ELI Policies and Procedures for the policies that govern your enrollment and the services available to you.

ELI Exam Passes:

You are expected to take your examinations at one of the NVCC campus Testing Centers. Be sure to allow enough time to complete your exam before the Testing Center closes; Testing centers have specific policies relating to the administration of ELI exams. Testing Centers will NOT let you take an exam if you bring your children.  This is an issue of liability.

For Testing Center locations, hours of operation and policies, click here .

At all Testing Centers, you will be required to show photo identification to take your examination. This may be an official driver's license, a DMV ID, or a military ID. You will also be required to provide the appropriate Exam Pass, which is located on your course web site or in the Syllabus, and your NovaConnect ID (also called your Student Number and EmplID). To look up your NovaConnect ID before you go to the testing center, go to /.

If you have received a W grade, you must have written permission from your instructor to take exams. Be sure to take this permission with you to the Testing Center to take the exam.

Using Technology:



All NVCC students automatically receive a student email account through the Virginia Community College System (VCCS). If you use email for course-related correspondence, you must use this account (instructors will not reply to non-VCCS accounts). For information on how to set up and access your account, go to , or call the IT Help Desk at (703) 426-4141.

The videotapes are on reserve for your use in the NVCC campus Learning Resource Centers (LRCs). Before you go to view a tape, be sure to call the LRC to make sure of the hours of operation. Please note that there are a limited number of tapes and playback machines in the LRCs.

There are 20 comprehensive videotapes keyed to the text by section. Also, an instructional graphing calculator videotape will be available to use throughout the course. It is a good idea to view these tapes after you have studied the instructional material from the text or when you are having difficulty with a particular math concept.

The sections contained in each tape are as follows:

Tape Number
Text Section
