Whаt structure is indicаted by the tip оf the metаl pоinter?

I hаve reаd the entire syllаbus fоr this cоurse and I fully understand what is expected оf me and am aware of all important dates and deadlines, including withdrawal, homework, and exams. I understand the course runs on a Monday-Monday academic week closing at 11:55pm. This academic week can shift during the course due to breaks and holidays.  I am to submit each week a writing assignment and 2 discussion postings (one to the original prompt and to at least one of my classmate's posts). I understand the midterm exam runs April 1-8 closing at 11:55pm and the final exam runs April 29-30 closing on Tuesday at 11:55pm.  Honorlock will be the proctoring application. No exceptions. I understand I must watch a theatrical performance and write a 3-page review about the production.  The paper is due April 29th at 11:55pm. I hereby affirm my understanding of expectations for this college-level class and that all standards of academic performance and behavior will apply to this class. I understand that it is my responsibility to complete paperwork should I need to withdraw from this course and that I must do so before April 17, 2024. After which date, I will receive the grade I earned. I confirm that when I miss two consecutive weeks of any assignment- discussion and/or writing assignment, I will receive a warning to drop the course. After missing the third assignment, the instructor will withdraw myself from the course for non-participation. I am aware that failure to submit my work by the indicated deadlines in the indicated syllabus will result in a zero for that assignment. I understand that late submission of work is not accepted after one week of the deadline and that there will be no make-up exams or papers without prior notification to the instructor and that valid supporting documentation may be required. I understand that I am responsible for making sure my assignments and exams submit successfully on the course site.  Unable to access the internet is not an excuse to miss work.  Failure to post work on time will result in a zero. I understand that cheating and plagiarisms is a violation of the academic honesty code and realize that any infraction of this code will have repercussions as indicated by this syllabus. Additionally, I understand that as a student in a college-level course, FERPA regulations apply. In addition to above agreements, I affirm, by my signature, that I have received a copy of the syllabus for THE 101. I also affirm that I am willing to accept additional addendums to this syllabus or schedule, under the discretion of my instructor.  Upon reading this statement, please sign your name.
