It means that if you notice a grading mistake on your worksheets/exams, you will have 1 week (for midterm exams) to submit your concerns to me over CANVAS/email. I will review your exam if you submit your          concerns within the regrade grace period.

You are allowed 4 regrade attempts per exam, with each regrade attempt limited to one rubric item. Additional regrade attempts are not accepted.

Missed Exams/Quizzes

It is your responsibility to be aware of all exam dates and times and ensure compatibility with your schedule. There are no make-up exams, except for serious medical emergencies.

Mental Health and Wellness

Many students experience a  range of issues that can cause  barriers to  learning, such as strained relationships, increased anxiety, alcohol/drug problems, depression, difficulty concentrating and/or lack of motivation. These mental health concerns or stressful events may lead to diminished academic performance or reduce a student's ability to participate in daily activities. UCLA offers services to address these and other concerns you may be experiencing. If you or someone you know are suffering
