Homework Assignments All assignments are on the syllabus, which is posted on my web page. 
  • Practice homework: I strongly suggest that you attempt all assigned problems as the tests will reflect these problems and any other problems done in class. Ten to fifteen minutes will be allotted at the beginning of each class so that you may ask questions over the previous class meeting's assignment. There is no way that I can answer all questions at this time, so see the section on where to get help.  
  • Turn in homework: The due dates for the turn in homework (which is sometimes distinct from the practice homework) will be given with each assignment. No late homework assignments will be accepted. You have two ways to makeup a zero on homework. One way is that I "may" assignment bonus homework (which are optional.) The other way is that I will drop the lowest 4 homework and or quiz grades before computing the final homework/quiz average. But, you may turn the assignments in early by email, fax or sliding under my door  before the end of class on the due date.
  • Reading Assignments: I strongly suggest that you read the sections before we discuss them in class. I may assign some reading assignments for a grade.
Quizzes Short quizzes will be over the previous class meetings lecture and homework material. The objective for quizzes will be to check for understanding of the basic material (homework and reading assignments), and thus will be much simpler than exams. No makeup quizzes will be given. However,  as described above I will drop the lowest 4 homework and or quiz grades before computing the final homework/quiz average. 
Attendance Beginning on the 2nd week of classes I will take daily attendance. At the end of the semester, if you have not missed more than 4 class meeting, then I will replace your lowest test grade with your final exam grade (if it is better). Also in the event that you are absent, visit this syllabus online to see what content and assignments you have missed.
Where to get help 1. My office hours are for all of my students' to ask questions.
2.  The Collaborative Learning Committee Center in S735 offers tutoring  (look for the tutoring hours about the 3rd week of the semester.)
3.  Try study groups with students in our class.
Statement on reasonable accommodations UHD adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with disabilities.  Students with disabilities should register with the office of Disabled Student Services and contact me in a timely manner to arrange for appropriate accommodations.

Course Content and Tentative Dates: The rest of the information will be filled in throughout the semester. In the event that you are absent please check this website for assignments and content covered.
