Email me with the following subject line:
LASTNAME Class-Abbreviation Date of Absence Absent
Let's say
Your subject line would look like this:
Johnson CHAU Nov. 10 Absent
or,
Johnson CHAU 11/10 Absent
That way I can easily find it and record your "excused absence" date at the end of the course, when I record the grades.
Always use a proper subject line when contacting me, please!
