April 16:

Please note that the Final Examination for the course will take place on

 

Saturday, April 25, 2015 from 9:00 AM to 12 PM in ACW 006.

 

The exam will be comprehensive, covering the entire course material

 

covered in class according to the Course Schedule with an emphasis on

 

the more resent material covered after Test #2. If less common formulas

 

are needed on the exam, then those will be provided on the exam paper.

 

There will be several questions, some with a few parts. Marks for each

 

question will be indicated. You have to show all your work and should

 

explain your solutions where appropriate. Unofficial final grades for the

 

course will hopefully be posted to the course web page by May 08, 2015.

 

I will be holding an additional office hour on Monday, April 20 from

 

12:00 to 1:00 PM to answer your questions.

March 03:

Last night, in a very large membership meeting, all three units of CUPE 3903 voted

 

not to send the employer's final offer to a formal ratification vote. Overall, the vote was

 

70% against sending the offer to ratification vote. The union executive then decided

 

to call the strike, given that it had a strike mandate in hand from earlier in February.

 

That means that, as of Tuesday March 03 at 12:01am, CUPE 3903 is on strike.

 

The University’s Senate Executive decided on February 27, 2015 that all academic

 

activities, including classes are cancelled until the strike is settled. Unfortunately,

 

at this point there is no way to know how long the strike might last. In the meantime,

 

even though it is difficult, I strongly recommend that you take this opportunity to review

 

course material covered up to now, catch up with readings if you've fallen behind, and

 

even read ahead, and continue to work on your assignments. Although due dates are

 

frozen, course work will be due when we return to classes. Keeping up with work will

 

make the transition back to classes a little less shocking.

 

Please distribute this message to your class mates. Thank you.

March 02:

As it was promised in the last class, I am making solutions to the questions

 

of White and Green versions of Test #1.

 

Also, please click here to see your score for Test #1.

February 28:

Please note that the Department of Mathematics and Statistics will be hosting

 

Science@50 anniversary event on Tuesday afternoon. The event will include

February 08:

As it was announced in the class on Thursday, we will write Test #1

 

during the lecture period on Thursday, February 12 in the two class

 

rooms as follows:

 

- family name starting with A - K: CLH J;

 

- family name starting with L - Z: CLH K.

 

On the test you will be responsible for all the material covered in class

Homework  

Throughout the term, recommended practice exercises will be posted to the Announcements section. In order to develop your understanding of the course material you must do all assigned exercises. These will not be collected for grading and hence will not directly affect your grade. However, it is extremely important that you complete all assigned exercises. Do not memorize them. Rather, learn how to solve problems like them. Learning Mathematics is not a spectacular sport, it is a participatory event. There is nothing like a bit of computation to strengthen understanding in mathematics! Successful students must keep up with homework and seek help for points they do not understand as soon as possible. Do not fall behind! It is recommended to read the relevant sections of the textbook before every class. Next to the classes, working out the answers to the exercises is the most important preparation for the tests and exam that will contain for the most part but not exclusively, questions very similar to those from the textbook. It is quite practical to work on your own or together in small groups. Each student should do at least two hours of independent study for every lecture hour. The amount you learn in this course and the grade you receive will be proportional to the amount of time you spend working on exercises.


Exams Information

Lecture/Exam Rules:

All internet connected and other distractive electronic devices (cell phones, pagers, head phones, digital dictionaries, CD players, laptops) need to be turned off during class, i.e. during lectures, tutorials, tests and exams. All such devices as well as all books, papers, knapsacks, and briefcases must be left at the front of a lecture hall during tests and exams. Anyone caught with electronic devices will be charged with Academic Dishonesty (see the next page). The only items you may have at your seat during exams and tests are pens, pencils, eraser student ID and purses. Notes need to be taken manually; use of cellphone cameras in class is not allowed. You are responsible for all material covered in lectures.
Note: Photo identification and signing-in are required at all tests and exam.

Final Grade:

The official grades at York University are LETTER grades. Qualitative descriptions of these grades can be found in the York Calendar at this link.
Your test marks will be on a numerical scale because these have to be weighted and averaged in various ways, but THERE IS NO AUTOMATICPREDETERMINED CORRELATION BETWEEN NUMERICAL GRADES AND LETTER GRADES in this course. In particular, the "numerical" grades you receive are NOT to be interpreted as percentages; they are merely 'raw scores'.
 When the tests are returned in class, the distribution of'raw scores' will be announced along with an approximate conversion to letter grades. The median letter grade for the course will likely fall between C and C+. 
The composition of the final grade is as follows:
Two Tests (80 minutes each written tests held in lecture periods): 25% + 20% (Tentative dates for the tests: Thursday, February 12 and Tuesday, April 07, 2015);
Final Examination 
(three-hour exam scheduled by the Registar's Office): 55% of the overall grade, will take place in April 2015, during the examination period.
Note: Students have five days from the date of the return of test papers to appeal their marks. Some test papers (randomly selected) are photocopied before they are handed back, so we can detect subsequent alterations. Also, to encourage good exam performance: once you have written both tests and your final exam grade is higher than your average test grade, your final exam will be counted as 60% and each test as 20% of your overall grade for the course.

Make-up Policy:

No permission will be given to a student to write tests in advance of their scheduled dates. No make-up will be done for the tests. A missed test will be counted as zero, except under extreme circumstances in which case the corresponding percentage of the overall grade will be "forwarded" to the final exam. If you miss a test for medical reasons, you must turn in within one week following the test date the Attending Physician's Statement form provided here after getting it filled in by your doctor. No other type of medical note will be accepted. However, missing tests is extremely dangerous and not recommended. As experience has shown, students who miss class tests because of some 'mysterious illnesses' will usually average 30% on the final exam.
Student who misses the final examination will be allowed to write a make-up exam only if both of the following conditions are met:
   1)
 the student notifies me (raguimov@mathstat.yorku.ca) or the Department of Mathematics and Statistics (Undergraduate Office, N502/503 Ross Building, 416-736-2100, Ext. 55902 or 33969) in advance that the exam will be missed;
   2)
 the student submits within one week following the exam date the Attending Physician's Statement form provided here after getting it filled in by his/her doctor.
Students who miss the final examination and do not meet both conditions will receive a grade of F. It is student's responsibility to fill out and submit the 
Deferred Standing Agreement form.
Note: Do not make vacation/job plan until the final exam date is known: having a plane ticket for Banff or Hawaii on April 18 is NOT a legitimate excuse for absence from a final exam on April 23.


Religious Observance and Accessibility:

Special needs students, please identify yourselves to the course instructor as soon as possible. York University is committed to respecting the religious beliefs and practices of all members of the community and making accommodations for observances of special significance to adherents. If any of the dates specified in the course schedule for in-class tests pose such a conflict, students should contact me (raguimov@mathstat.yorku.ca) within the first two weeks of classes. Please note that if the final examinamtion date poses a conflict, students must complete the Final Exam Accommodation form, which can be obtained from the Registrar’s Office. 
Please refer to appropriate Senate documents on:
  1) Course requirement accommodations for students with disabilities, including physical, medical, systematic learning and psychiatric disabilities;
  2) Student Conduct Standards.
Note that York University welcomes feedback on accessibility issues. Your feedback may be provided by sending an e-mail to: mathstat@yorku.ca

Academic Honesty:

Students are responsible for familiarizing themselves with University Policies and Regulations. Conduct that violates the ethical or legal standards of the university community or of one’s programme or specialization may result in serious consequences. Refer to the Senate Policy on Academic Honesty. Photo identification and signing-in are required at the all tests and exam.

Communication:

Individual questions can be discussed by e-mail or in person after class, or during office hours. Please send all e-mail notes as plain text within the body of the message. Do not send attachments or HTML-formatted e-mail. No texting, please. Also, if the name of your account is an alias, I will not know who the mail is from unless you sign it; it also risks being accidentally discarded as junk mail. The course web page will be up-dated regularly to include important announcements made in class, such as the material to be covered on the tests. E-mail notes requesting such information contained on the web page will be answered the last.
