HOMEWORK

PLACE ALL OF THE ASSIGNED AUTHOR's EXAMPLES AND SOLVED PROBLEMS INTO A THREE-RING NOTEBOOK and/or save in ELECTRONIC VERSION. Instructor will ask you to submit several of those problems (randomly chosen) for grading at each exam: homework problems are part of the exams.

Assigned problems will be posted on our webpage soon after most lectures. 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.

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 SIX (6) EXAMS. Exams are given on Wednesdays, except for the first week of the term. To ensure fairness in your evaluation, the lowest exam score will be dropped

Exams include all the materials covered until Monday (inclusive) the week of the exam.

1. Electronic solutions in PDF can be submitted to course's site on CANVAS. Hand-written solutions are also acceptable.

2. Exams are solved individually during the assigned times. Open-books open-notes.

3. Laptop computers can be brought into the exams should electronic solutions are submitted.

GRADING

THE GRADE FOR THE COURSE WILL BE BASED ON THE EXAMS, with homework problems (randomly chosen) being part of the exams.

1. To ensure fairness in your evaluation, the lowest exam score will be dropped.

2. Participation in course discussions, demonstrated engagement in the course materials, demonstrated effort, and other positive contributions made to the course will strongly be taken into consideration for grading.
