¡Reading should be completed before lecture.¡There are no reading quizzes, but readingahead is highly recommended, and will makelecture and discussions more productive.¡Tests may include material not explicitlycovered in class.

¡Weekly homework assignments are to becompleted online using WileyPLUS. Allassignments must be completed online by11:00pm on Thursdays.¡You are allowed to work with other students onthe homework, but each student must calculatethe solutions to his/her own questions andsubmit the answers on WileyPLUS.¡WileyPLUS homework is electronically graded –ensuring a totally level playing field.

Self-Guided Physics Practice (Up to you)Homework Assignments (Required)Electronic Versions of Chapters

¡Common Issues:§ Not carrying enough decimal places through inmathematical calculations Math problems require the answer to be within 2% of theexact numerical value§ Grading problems If you believe your problem was misgraded, tell me and I willfix it!§ Browser issues When in doubt, log out and clear all cookies, then log back in When all else fails, contact Wiley Plus tech support

¡Homework will include conceptual (one chanceper problem) and mathematical (three chancesper problem) questions¡There will be 12 math and 12 conceptualassignments§ Only the top 11 scores for each will count toward thefinal grade¡There are practice (ungraded) math andconceptual assignments available now on WileyPlus

¡The laboratory assignments are a key part ofthe course, to be held under the supervisionof your teaching assistant, who will alsograde the laboratory reports.§ Remember to complete pre-lab questions beforelab!¡Only 9 of 10 labs will be counted towardgrading, however, there will be absolutely nomake-up labs.
