Exams: The exams will be closed book, closed notes. There will be two midterm exams and a Final exam. Midterm exams will be given on Fri. Feb. 20, 6-8 PM and Fri. Apr. 10, 6-8 PM. BOSTON UNIVERSITY EK307 A2 S2015 College of Engineering Missed Exam Policy: Absence from an exam can be excused only for reasons of illness, or unavoidable travel. Permission of the instructor in advance is required. In the event of illness, a doctor’s note is required. Homework: Weekly homework assignments will be due Wednesday for EK307 A2 at the beginning of class. A homework cover page must be stapled to the front of each homework set. Late homework will not be accepted. Homework submissions must be neat and well-organized. All work should be shown, including circuit diagrams. Each solution should clearly indicate the technique used and assumptions made. The “right answer” by itself is no solution and will earn no credit. Badly organized, illegible, or unclear work will cause loss of credit. Final answers should be highlighted (boxed, circled, underlined, etc.). All students must comply with the University’s Universal Academic Conduct Code http://www.bu.edu/academics/resources/academic-conduct-code/. Lecture: Lectures may contain materials that are not in the textbook. Such materials may appear in homework and on exams. Discussion Sections: Discussion sessions will be held Monday, Tuesday, and Wednesday, 6-8pm, in PHO203. Labs: Lab information is found at: http://www.bu.edu/eng/courses/ek307/ Labs will meet weekly in PHO 105 starting the week of January 26. You are required to purchase an EK307 laboratory kit available at the counter in PHO105. You must also purchase a bound lab notebook, loose-leaf and spiral notebooks are not acceptable. Each lab will need to be signed off by a GTA. Late lab reports will not be accepted.
