I am having difficulty assigning letter grades to my mid-term exam
It sounds like you are wanting to use letter grades instead of point values for your mid-term. If that's right, you can edit the midterm to change this. Beneath the Points Possible field and Assignment Group is the "Display Grade As" option. You can change that to letter. For a more in-depth explanation and screenshots, check out this article: How do I add or edit details in an assignment? Go to the section about "Select a Grading Type."
If that's completely off-base, could you provide some more details?
Many thanks for your email.
