I'm using the
exam documentclass, and I'm wondering if there is a way to label the questions with a, b, c, ... instead of with 1, 2, 3, ...
What I have often found is that we could redefine
\questionlabel, but that still involves a counter (natural number). Example taken from How to change the question number from just '1' to 'Question No. 1.' in the exam class?
Maybe there is a way to convert the number from
\thequestion to a letter from the alphabet?
