Text Formatting ⇒ Set question and part number in Exam class

[Singularity]

How best can I number the following MWE to question 9b?

I am using the exam class. I am adding an additional question to a quiz, so I want to number it as question 9b. I see from here how to set the question number. But, it won't let me create question 9b (probably because question number must be numeric).

So I numbered the question 9 and added parts. Now I want the part to start as b. But I cannot find anything in the exam's documentation on how to set the part number. In fact, I can't find anything which discusses how to set the question number (which would lead me to the area on how to set the part number).

So, part (b): where did you find how to do that in exam's documentation, so I don't have to ask questions every single time I need to do something.

\part Divide $v^6+1$ by $v-1$.

Counters always have a numerical value, just the output changes. \begin{parts} will reset the counter for parts (partno), so setting the counter has to after starting the parts.

Where or how to find it? I simpply scrolled the toc of the documentation, and »Customizing the numbers« caught my eyes. And there is the relevant counter (partno).

I read that section, but I didn't understand the key sentence (I'm going to blame the strange spacing).
