Email Address: It is important that you enter your official “vt.edu” email in Hawkes. There is an option for a secondary email, which can be any additional address where you want notifications sent. Student ID: Please enter your VT Student ID Number (90########) as your Hawkes Profile Student ID. See the “Student_Quick_Start_Guide.pdf” on the course website for instructions and information on how to get your access code. Hawkes certifications are due (i.e., must be completed) by 11:59 pm (before midnight EST) on the scheduled day. The time that counts is the time you submit your completed certificate via the Internet to the Hawkes website and NOT the time you complete the certificate on your computer. Always check your Hawkes Progress Report to ensure that you received credit for the completed lesson(s). GRADES for Hawkes Lessons/Certifications: You get “certified” if you answer a sufficient proportion of the questions correctly. Full credit is given for certificates completed and submitted on time. Half credit will be given to Hawkes certificates submitted within one day late. No credit will be given for certificates submitted more than one day late. The highest 34 scores will be used when computing your Hawkes average. If you experience difficulties with the Hawkes Learning lessons or accessing the Hawkes Web Platform, you should contact Hawkes Learning Technical Support. Quizzes: There will be 12 online quizzes assigned during the semester. These quizzes will be based on the recommended problems as well as the material discussed in the lectures. You can take each of the quizzes up to three (3) times and the highest/best score will be used when calculating your quiz average. HINT: I suggest you work the recommended problems before attempting/taking the quizzes. The lowest two quiz grades will be dropped when computing your quiz average. Missed quizzes cannot be made up under any circumstances. Midterm Exam and Final Exam Policy: All midterms and final exams are to be completed on the Hawkes Learning Systems website and are due by 11:59pm (before midnight EST) on the scheduled due date. Two attempts will be allowed for each of the three midterm exams (questions will change for the second attempt). The higher of the two scores will be recorded. Only one attempt will be allowed for the Final Exam. If you know that you will be unable to take an exam at the specified time, arrangements must be made prior to the exam. Documentation must be provided if you are unable to complete an exam in the scheduled time period. The final exam is comprehensive. Statute of Limitations: You have one week after an assignment is graded (7 days… not 7 business days) to see me to discuss any grading concerns (recording error, errors in grading, etc.) that you have for an assignment (test, quiz, homework, etc.). I strongly encourage you to review all your assessments when they have been made available to you. HONOR SYSTEM POLICY The Undergraduate Honor Code pledge that each member of the university community agrees to abide by states: “As a Hokie, I will conduct myself with honor and integrity at all times. I will not lie, cheat, or steal, nor will I accept the actions of those who do.” Students enrolled in this course are responsible for abiding by the Honor Code. A student who has doubts about how the Honor Code applies to any assignment is responsible for obtaining specific guidance from the course instructor before submitting the assignment for evaluation. Ignorance of the rules does not exclude any member of the University community from the requirements and expectations of the Honor Code. For additional information about the Honor Code, please visit: https://www.honorsystem.vt.edu/. All assignments submitted shall be considered "graded work” and all aspects of your coursework are covered by the Honor Code. All projects and homework assignments are to be completed individually unless otherwise specified. NOTE: You may not copy, photograph, or in any way capture physically or electronically any part or parts of the quizzes, quiz questions, tests, test questions, or anything related to an assessment as doing such would constitute a violation of the Honor Code.

Please note that Zoom sessions are part of our course and are governed by the same rules and guidelines as traditional in-person activities. A few suggestions: • Please attend office hours! You do not need to have questions (although you’ll get more out of it if you do!). You are welcome to simply show up, learn from each other, and enjoy each other’s company (virtually). • Please mute yourself when joining the meeting. • In large meetings, you are not required to show your video. If we happen to have a smaller group, it really helps to see your face :-) O If you do turn on your video, please make sure your environment is appropriate and make sure to inform others in your video space that they will be recorded. • Note: Some people are under the misimpression that they don’t “get” math and/or statistics. This is poppycock - it just takes some people more time to really understand some mathematical concepts. Regardless, if you think of yourself as someone who doesn’t get math or if you expect this class to be difficult, please come to office hours as often as possible. This class rewards effort – make the effort. PREREQUISITES for BIT 2405 The stated mathematical prerequisites for the sequence BIT 2405, 2406 is Math 1524. There are other possibilities, though. If you have more questions, please see Pamplin’s Undergraduate Office in Pamplin 1046. Other Notes and Comments • All students will be held to the university’s Well-Being Commitment. Specifically, masks will be required in the classroom until further notice. • Students are expected to check email and the course page on Canvas regularly for updates on class assignments, handouts, and announcements. • Professional and respectful classroom behavior is expected and required. • All emails must include the course number in the subject line. All emails must be from a VT email address. • There will not be any extensions for quizzes and tests. HW can be turned in late at a penalty (no credit after 1 day late).
