Course Policies: If you have taken CHEM 1105 before, you may be eligible for a lab exemption. Talk with me before the first scheduled lab to verify whether you are exempted or not. If you are unable to take a quiz or test, you must contact me before the quiz or test is scheduled to start . If I am unavailable, please leave a voice mail message or send an email, including a phone number where you can be reached. A medical certificate (dated the day of the absence) or other relevant documentation will be required upon your return to school. When said documentation is provided, the weights of the other term tests will be adjusted so you will not be penalized for missing that test. If you must miss a lab, contact your lab instructor beforehand to indicate that you will miss the lab then, upon return to school, provide documentation to the lab instructor. More than three labs missed for any reason will result in a grade of incomplete being assigned for the laboratory portion of the course. Labs or tests missed for which documentation is not produced will be assigned a grade of zero . Students requiring accommodation for a disability in chemistry 1105 must ensure that the accommodation notice (from a Disability Advisor) covers both the lecture and the lab. A lab assistant accommodation must be approved by a Disability Advisor; the student must arrange this before the first lab . The Chemistry Department may provide suggestions regarding finding a suitable lab assistant, however finding a lab assistant remains a student responsibility.
