However, if a student provides a legitimate excuse well in advance, scores will be prorated. Work with due date should be turned in at the beginning of class on the stated due date. Late work will not be accepted and will be deemed work not submitted.<\/li>\n<li><span style=\"text-decoration: underline\">Policy on class attendance<\/span>: Requirements for class attendance and make-up exams, assignments, and other work in this course are consistent with university policies that can be found in the online catalog at: https:\/\/catalog.ufl.edu\/ugrad\/current\/regulations\/info\/attendance.aspx.<\/li>\n<li><span style=\"text-decoration: underline\">University&#8217;s honesty policy<\/span>: UF students are bound by The Honor Pledge which states, &#8220;We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honor and integrity by abiding by the Honor Code&#8221;. On all work submitted for credit by students at the University of Florida, the following pledge is either required or implied: &#8220;On my honor, I have neither given nor received unauthorized aid in doing this assignment.&#8221; The Honor Code (http:\/\/www.dso.ufl.edu\/sccr\/process\/student-conduct-honor-code\/) specifies a number of behaviors that are in violation of this code and the possible sanctions. Furthermore, you are obligated to report any condition that facilitates academic misconduct to appropriate personnel. If you have any questions or concerns, please consult with the instructor or TAs in this class.<\/li>\n<li><span style=\"text-decoration: underline\">For students with disabilities<\/span>: Students requesting classroom accommodation must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accommodation.<\/li>\n<li><span style=\"text-decoration: underline\">Students&#8217; evaluations of the course<\/span>: Students are expected to provide feedback on the quality of instruction in this course based on 10 criteria. These evaluations are conducted online at https:\/\/evaluations.ufl.edu. Evaluations are typically open during the last two or three weeks of the semester, but students will be given specific times when they are open. Summary results of these assessments are available to students at https:\/\/evaluations.ufl.edu\/results.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><span style=\"text-decoration: underline\">Disclaimer<\/span>:\u00a0I reserve the right to change the above policies if situations warrant.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Homework problems by section:<\/p>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">Homework 1 (Due 09\/15\/17): 1.222, 1.241, 1.253, 1.255, 1.6, 1.12.<br>\nHomework 2 (Due 10\/27\/17): 1.25, 1.33, 1.34,1.49, 1.51, 1.61, 1.62, 1.63, 1.64, 1.152, 1.153.<br>\nHomework 3 (Due 12\/01\/17): 1.159, 1.160, 1.162, 1.169, 1.181, 1.183, 1.192, 1.193, 1.198, 1.201.<\/p>\n\n\n\r\n\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/section>\r\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":311,"featured_media":0,"parent":8,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"featured_post":"","footnotes":"","_links_to":"","_links_to_target":""},"class_list":["post-439","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/pages\/439","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/users\/311"}],"replies":[{"embeddable":true,"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/comments?post=439"}],"version-history":[{"count":10,"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/pages\/439\/revisions"}],"predecessor-version":[{"id":1568,"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/pages\/439\/revisions\/1568"}],"up":[{"embeddable":true,"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/pages\/8"}],"wp:attachment":[{"href":"https:\/\/people.clas.ufl.edu\/pilyugin\/wp-json\/wp\/v2\/media?parent=439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
