Chemistry 152 - Grading |
||||||||||||||||||||||||||||
Grades for CHEM 152 are earned according to the following scale of total points (not %). The number of total available points will be 1000 points or greater.
The grades for Chem 152 and Chem 152L are completely
independent of each other.
The 1000 points is the sum of your four highest scores out of five categories, including four exams and one average "activities" score. The activities will consist of quizzes, in-class activities, and occasional take-home activities. Your scores on these activities will be trimmed (removing the top and bottom 10% of scores), averaged, and normalized to a total of 250 points at the end of the semester. |
Originality. All work must be original and your own. Penalties, such as automatic grades of zero, will result from cheating, copying, plagiarism, or deceit of any kind (SDCCD Policy 3100). Cheating on an in-class quiz or exam includes use of pre-written hints or notes, looking at another student's paper, allowing (or not preventing) another student to copy your answers, or use of a programmable calculator (see page 1). Collaboration. I expect and encourage collaboration among you and your peers while working on in-class and take-hom activities, but not on quizzes or exams. In any case, the work you submit to me must be your own, not a copy from another student. The guideline is that you should have no trouble explaining or repeating work that you turn in. Plagiarism. If you look at someone else's paper during an exam or quiz, or copy directly from another student on any assignment, then you and the person from whom you copied will both earn a zero on the assignment without notice or exception. Mesa College may also wish to pursue academic sanctions, expulsion, and/or legal proceedings. Please be fair.

Solutions and explanations should be clear enough so that one of your peers could easily follow what you did if they had not worked the problem before. When
a quiz, exam, in-class or take-home exercise calls for a calculated
answer, no matter how simple, you increase your chances of arriving at the correct answer (and receiving partial credit) if you show a clear, step-by-step solution using dimensional analysis (unit conversions). This means that you need to show
the units (dimensions) on each number and the conversion factor or
equation used in each calculation. 
Make-Up Work. Make-ups are not available for exams or quizzes, whether or not
your absence is excused. So if you miss an exam or quiz, you
get a zero. Fortunately, you can drop an exam if your activities total is higher. If you miss a class due to an excused absence, you may submit late take-home and in-class activities, with grade reductions of 20% and 50%, respectively, per calendar day starting at the due date and time.
