Another try to include image.

You could try

\def\AMCformQuestion#1{\vspace{\AMCformVSpace}\par\noindent\hangindent=2.5em\hbox to 5.8em{\hfill \bf Frage #1:}}

It does not add the zero but all the squares are aligned irrespective of the numbers of digits.

Oops. I forgot to mention we are using AMC-TXT.

We did it kinda the way you mentioned back in the days we were using LaTex. I haven't yet figured out how to include this in AMC-TXT without getting tons of compiling errors.

Woops. It works in the "LaTex-Preambule:" command. It's better overall but still looks a little messed up

I hoped for something like %d that could be changed to %0d ^^

This is not a perfect solution because the strings 11 and 08 do not have the same width with proportional fonts.
If you need Frage to be left-aligned and the number to be right aligned, you can try something like

\def\AMCformQuestion#1{\vspace{\AMCformVSpace}\par\noindent\hangindent=2.5em\hbox to 5.8em{\bf Frage \hfill #1:}}

With hbox to 3.8em this looks perfect! Thank you! :)

Hello,
I did not succeed to make such a grid.
Could you share the source code ?
Kind regards
