GRADING

THE GRADE FOR THE COURSE WILL BE BASED 50% ON THE HOMEWORK and 50% ON THE EXAMS.  Participation in course discussions, demonstrated engagement in the course material, demonstrated effort, and other positive contributions made to the course will strongly be taken into consideration for grading.


HOMEWORK


SAVE AND ORGANIZE ALL OF THE ASSIGNED HOMEWORK PROBLEMS AND SOLUTIONS IN ELECTRONIC FORMAT.  Instructor & TA will ask you to submit several of those problems (randomly chosen) for grading.  In some cases, some homework problems will be part of the exams.

     ·  Solutions in PDF are submitted to course’s site on CANVAS

Assigned problems will be posted on our webpage soon after most lectures, normally by no later than early afternoon.  Theory developed and example problems done in lectures should normally provide guidance to complete assigned homework.  Occasionally, the assignments will cover materials that we have not yet covered in lecture.

Homework will be collected twice during the week.  The schedule of when homework is due and when it will be graded and returned is as follows:

Everything assigned before, including

Day due

Day returned & answers posted

Monday

Wednesday

Friday

Tuesday / Wednesday

Friday

Monday


Good faith collaboration on the homework assignments is encouraged.  In good faith collaboration, students should first make serious attempts to solve the problems on their own, and only then discuss the problems with one another to clarify difficulties they may have had.  If the collaboration is done properly then, even though students have worked together, the details of their solutions should still be quite different.


EXAMS


THERE WILL BE SEVEN (7) EXAMS.
  Exams will be given on Wednesdays during our Teleconference times. 

Each exam will include all the materials covered until Monday (inclusive) - the week of the exam.

     ·  Solutions in PDF are submitted to course’s site on CANVAS

Notes:
1) Exams are done individually without collaboration during our Teleconference times
2) To ensure fairness in your evaluation, the lowest exam score will be dropped
