Remote Teaching Enacted

Due to Auburn University's transition to 100% remote teaching (because of the coronavirus situation), much has changed with regard to my lecturing of these classes. Much of the original information below is now irrelevant. Here are the main items you need to know going forward (from 16 March onward):

Exam #4 (Chapter 7) via ProctorU

Here are instructions on how you will take the WebAssign Test #4 (Chapter 7) through ProctorU and here is a direct link to the test.

Students should read this document to familiarize themselves with this service.

Once you login to ProctorU, you will search for the test by name.

The test name is MATH 1150 Chapter 7 Test. It will show Lora Merchant as the instructor.

Please double check that you are signing up for the time you want (am/pm) and verify the timezone if you are in a different timezone.

Unlike other assignments, you can only take the test on the due date which is 4/8/2020.

The testing window is set up in ProctorU from 8am to 9pm CENTRAL TIME. Even though WebAssign shows the due time at 7pm, the last time to sign up in ProctorU is 5PM. You can go ahead and make your appointment. If you wait until the day of the test, there may be some wait time so plan accordingly.

Also, the only two types of calculators allowed are the TI-30XA and the TI-30XIIS. You will not be allowed to test with any other calculator.


This class is participating in the All Access program which gets you access to a digital copy of the textbook for this class. Instructions on how to login to "WebAssign" to access this e-textbook are here. The Class Key for this particular class is: auburn 6401 4642. You are currently OPTED IN to be charged for this material. Instructions on how to opt out are here.

If you are having trouble logging into WebAssign (because you previously opted-out, or some other reason), please let Dr. Merchant (the MATH1150 coordinator) know by emailing her at Dr. Merchant has also put together this document that details some "tips and tricks" about WebAssign that you should read.

Office Hours/Zoom Video Conferencing

Office hours are now being held via Zoom video conferences (at the same times as my original office hours: 11:00am, MTWF). To join the "Zoom meeting" at those times, here is the invitation link. A "quick start user's guide" to the technology is here. My office hours are at 11:00am MTWF or by appointment. My office (313E Parker Hall) is a bit tricky to find. When you enter Parker Hall through the main front (north) entrance, go up the stairs. You will be in the front hallway of the 3rd floor. On the inner wall of that front hallway, between the doors for the Men's and Women's Restrooms is a large door labeled "313". My office is down the hallway behind that door.

If you need to reach me via email, my email University email address is: I do my best to check this email at least once per day.

Spring 2020 Classes

I am teaching these sections of 1150 Pre-Calculus in Spring 2020:

Exam Answers

Below are the answer keys to the actual (not Practice) exams given in the class.

Practice Exams

Practice Exams are meant to give students an idea as to what type of problems (and roughly how many problems) will be on the actual Exams administered during the semester. Students should be familiar with all exercises from the sections covered in class, not just those on the Practice Exams. Any such problems may appear on the actual Exams.
Information below this point is likely irrelevant now...

Class Policies


There is no formal attendance policy. You are expected to show up to class every day. Any changes to test dates or other class policies will be announced in class. There is no online component to this class; I will occasionally send emails to the whole class with announcements, but all of the material I cover is done so in class, lecturing at the blackboard. I do not use WebAssign to administer any quizzes or homework. You should only need WebAssign/All Access to access a digital copy of the textbook for the class (as mentioned above).


There are no formal homework assignments, but you are encouraged to look over the problems I suggest at the end of each section relevant to what we are studying. Here is a tentative list of the problems I generally suggest through the entire semester (listed by section in the textbook). I will be happy to answer any questions about such problems in class, time permitting (or at my office).


I personally create and grade all regular tests for my class. You will not need Scantron forms for those tests. For a calculator you are only allowed to use the TI-30Xa, TI-30XA, or TI-30XIIS scientific calculators (as pictured to the right); this is a Math Department policy. This calculator is readily available at bookstores, department stores, and online. All phones must be turned off and stowed away during test periods. You should take your test with your particular class section (that is, do not show up to one of my other MATH1150 class sections trying to take the test at a different time).

Make-up Tests

If you are absent during a Test Day, you will only be eligible for a make-up test if you provide me with a valid, University-approved, excuse for your absence within one week of missing the original test. These valid reasons are typically limited to: Some examples of invalid excuses (I have had students try to use these before -- they were not excused): I am very strict about requiring documentation for missed tests. I do not require you to show up on non-tests days (although you should if you want to learn the material), but if you do not, within one week, provide me with a valid, documented excuse for missing a Test Day, you will receive a 0 (zero) for the missed test and not be allowed to make it up.

If you do provide me with a valid, documented excuse, then you will be eligible to take a make-up exam for that particular test, and we will schedule a time for you to take it as soon as possible.


There are five regular tests during the semester, each graded out of 100 points. The dates of the tests are tentatively on the Class Calendar, but they are subject to change (I will always give you at least one week's notice of an exact test date). The Final Exam is the uniform Final given to all MATH 1150 classes in the College of Sciences and Mathematics. It will be comprehensive and worth 200 points toward your grade in this class. The time and date of the Final Exam are also on the Class Calendar and also at this webpage.

The five tests and the Final Exam will allow you to accumulate up to 700 points throughout semester, and your total number of those points will be compared to the following chart to assign your final letter grade for the class as a whole:

Total Points   Grade
630 - 700        A
560 - 629        B
490 - 559        C
420 - 489        D
below 420        F
The points you earn on the tests and Final Exam will be the only factor in determining your grade for the class.

Be very clear on the following things:

I do not use Canvas to post grades. If you ever need to know your current grade in the class, talk to me after any class period, come by my office, or email me.

Additional Learning Resources

Below are additional resources that students may wish to take advantage of if they feel they are not learning the material well enough just from attending the lectures every day. Of course, studying the textbook could prove valuable as well.

Supplemental Instructors

The Supplemental Instructor program has undergraduate students who have advanced far beyond pre-calculus sit in on some pre-calc lectures, take notes, and then run study sessions for students. Regardless of which MATH1150 instructor or which section you have, you are welcome to attend any of the MATH1150 SI sessions.

The SI for MATH1150 this semester is:

COSAM Drop-In Math Tutoring

The Math Drop-In Tutoring Service is offered by the Math Department. Room locations and times are detailed in the linked flyer.

AU Study Partners

Auburn University offers a Study Partners Program at the main campus library. Information about this free program is at the provided link.
