Exams and Assignments

Homework assignments will be through MyMathLab.

There will be two midterm exams and a comprehensive final exam. The date and time to be announced later. Exams will be online. Students need to have a desktop or laptop computer with camera. I will email students the exams 10 minutes before the start time, and I will give them 10 minutes after the end time, for them to scan and email their solutions to me. During the exams, students need to keep zoom on, with audio and video on. The video should capture the student's face. The exam will be recorded.

It is the students' responsibility to find the best way for them to scan and email documents. My suggestion is to use their smart phones and some apps. In my experience for iPhones, the built-in Notes app works great. I have no experience with Android phones.

Exam 1 is on Wednesday September 30, 1:00 - 1:50 pm central time. It covers all topics in Chapter 8. The instructor will email students the exam at around 12:50pm. Students need to finish the exam and return their solutions back to the instructor via email, by 2:00pm. All students need to log into zoom and turn on the video. It is required that the video should capture the face/head of each student. For those students who have legitimate ODS documents or doctor's notes that allow extra exam times, the exam will be extended accordingly. For instance, those who need 200% exam time will have 1:00-2:50, and need to send back the exam by 2:50pm.

Exam 2 is on Wednesday Nov 18, 1:00 - 1:50 pm central time. It covers all topics in Chapter 10 and 11. The format is the same as Exam 1.

Final Exam is 11:30 am-2:00 pm Friday Dec 11 central time. It will be cumulative. All students need to log into zoom and turn on the video. It is required that the video should capture the face/head of each student. For those students who have legitimate ODS documents or doctor's notes that allow extra exam times, the exam will be extended accordingly. For instance, those who need 200% exam time will have 11:30-4:30, and need to send back the exam by 4:40pm.


Grading Policy

Homework Assignments:       25%;

Two Midterm Exams:                25% each for a total of 50%;

Comprehensive Final Exam:  25%.

Policy on Missed Exams and Coursework

There will be no extensions of the deadline for homework, unless there are documented legitimated reasons.

A makeup exam may be given in the following cases subject to verification: a serious illness or medical emergency, a University-sponsored event, a religious event, a family emergency, or recalled to active military duty. A makeup exam should be scheduled at least one week in advance, unless it is due to emergency situations. You must email the documentation either before the exam or as soon as you return to class.

Attendance Policy

Due to the COVID-19 pandemic, this course will be delivered online via zoom meetings. Class attendance is required, but attendance will not be recorded or counted toward the final grade. Class participation is strongly encouraged. Students are solely responsible for any work missed during an absence. In order not to interrupt the class, no student is allowed for early departure, unless you get my permission in advance.

Please be aware that the UA Student Code of Conduct prohibits students from "Disruption or obstruction of teaching, research, administration, disciplinary proceedings, or other University activities, including its public-service functions, whether on or off-campus, and other authorized non-University activities that occur on University premises.” Disruptive or obstructive behavior in any class meeting, in-person or online, may be referred to the Office of Student Conduct for disciplinary action. In addition, please understand that without prior approval from the instructor, students may not record course content and/or post course content publicly, including on social media sites. Students who record and/or post course content without instructor approval may be referred to the Office of Student Conduct for disciplinary action.

Course instructors may choose to record class sessions for students enrolled in their class to refer back to, and for the use of enrolled students unable to attend class meetings. If an instructor chooses to record class sessions, students must be notified. Instructors should also notify students that when they participate in recorded online class sessions with their camera engaged, or utilize a profile image, they are agreeing to have their video or image recorded. If a student is unwilling to have their profile or video image recorded, it’s their responsibility to keep their camera off and to not use a profile image. Likewise, students who un-mute their audio input during class and participate orally are agreeing to have their voices recorded. If students are not willing to have their voices recorded during class, they must keep their mute button activated and communicate exclusively using the "chat" feature, which allows students to type questions and comments live. Instructors should also inform students that all recorded lectures, presentations, and class discussions are for viewing by members of this class section only, and may not be posted in any public forum or shared with anyone not enrolled in this class. Any student violating these rules may be referred to the Office of Student Conduct for disciplinary action.

Notification of Changes

The instructor will make every effort to follow the guidelines of this syllabus as listed; however, the instructor reserves the right to amend this document as the need arises. In such instances, the instructor will notify students in class and/or via email and will endeavor to provide reasonable time for students to adjust to any changes.
