Question setup
So do we not pay attention to the part that says 2 letter grades are consecutive if and only if they are adjacent.

Not sure I am understanding your question here but the rule that "two letter grades are consecutive if and only if they are adjacent in the alphabet" definitely applies.
So A and B are consecutive as are B and C, C and D and D and E.
Hope that helps! Please let us know if you have any other questions.
