COURSE EVALUATION/GRADING SCHEME

The Laboratory for Chemistry 1112 will consist of 12 laboratory experiments.  These labs will be worth 25 points each and are scheduled according to the attached sheet.  During the final laboratory period there will be a laboratory quiz worth 100 points.

 

 

 

                                                12 experiments x 25 points                        = 300 points

                                                Laboratory quiz                                = 100 points

                                                          Total                 400 points

 

 

For each experiment that is completed a laboratory report that consists of the data page, and the pre-lab exercise must be handed in at the end of the laboratory class meeting.  For each laboratory experiment, a grade will be available at the beginning of the next laboratory meeting after the lab report has been submitted.

 

 

 

GRADING:   The total number of points available in this course is 300

                 

 

The final grade will be assigned according to the percentage of points attained, that is 90% corresponds to a grade of A, 80% corresponds to a grade of B, 70% corresponds to a grade of C, 60% corresponds to a grade of D, and less than 60% corresponds to a grade of F.
