Posted Information (homework solutions, example exams, assignments):

At website (http://www.csus.edu/indiv/d/dixonr/C31/C31.htm)

 

Tentative office hours: Mon 12:00-1:00, Tues. 4:30-5:30, Wed 9:30-10:30.  The office hours for the lab instructors will be posted later.

 

Attendance:  Attendance in the lecture will not be taken.  However, it is to your benefit to attend the lectures and quizzes can not be made up.  In the lab, the instructors reserve the right to drop students who miss too many lab meetings, who fall behind because of attendance problems, or who are consistently late to lab.

 

Grading:

The lecture score will account for 55% of the total score with the remainder (45%) from the lab.

 

Lecture:

         2 midterms (100 points each)

         Cumulative final exam (150 points)

Exams missed due to exceptional circumstances can be made up on the day of the final exam.

         Quizzes (50 points total)

There will be six quizzes (five that count and each worth 10 points).  You will be able to drop your lowest quiz score.  The first graded quiz will be the diagnostic quiz, with the score based on the "resubmitted" quiz (You get a chance to correct wrong answers).

Homework (25 points total).  Text homework problems will be assigned but not collected, but you will be assigned one or two “additional” problems with each homework set that will be collected.  Homework is collected roughly every other week. 

 

Laboratory:

Laboratory Reports (85 pts)

Laboratory Notebook Grading (10 pts)

More details of the laboratory grading is provided in the handout, “Chem. 31 Laboratory Report Schedule”.

 

Assignment of grades:

The break-down of grades will depend on the class average (in other words be curved), but a higher class average will result in more high grades.  The following grading scheme (excluding +’s and –‘s) can be considered “typical”:

               A                                                    90 – 100%

               B                                                    78 – 90%

               C                                                    66 – 78%

               D                                                    55 – 66%

NOTE:  There is a minimum score requirement of at least 50% in both the lecture and laboratory sections to get a grade of C- or above.

 

Cheating in class:  Student caught cheating during quizzes or exams, falsifying lab data, or plagiarizing reports will be subject to punishment.  If you have questions on what constitutes plagiarism, see the instructor. Punishment may range from receiving a zero on the quiz/exam to expulsion from the university (see http://www.csus.edu/umanual/AcademicHonestyPolicyandProcedures.htm).

 

Prerequisites: Pass Chem 1A and 1B or equivalent with grade of C- or better.  Be prepared to show proof that you have met the prerequisites in lab.
