Yes. Start by discussing your concerns with the DRC Coordinator. With further explanation, you may agree that the accommodations are both reasonable and doable, but if unique aspects of your course were not fully considered, then alterations may be needed. If you still feel the accommodations are inappropriate, please review your objections with your department Chair and forward any additional opinions to the DRC office. The matter will be reviewed with appropriate administration. Do not unilaterally discontinue or refuse accommodations without formal administrative consultation and legal review.
