LaTex Exam: New to Latex - Indentation problem, fix is inelegant and inconsistent when the text goes over multiple lines

Question

I've been experimenting with the exam class as an alternative to word and am attempting to get the formatting as similar as possible to the Year 12 format by country uses. Below is an example of such:

Which produces:

It looks decent at first glance but when using qformat, the initial question text is indented. I used some sort of box and negative spacing to fit it but it doesn't perfectly align. Another problem is directly after the qformat, when the question text exceeds one line, the text between "Question X" and the first line of the question shrinks.

As I plan on producing documents on a large scale, I was wondering if there was a more elegant fix to replicate the Year 12 Exam style. If this isn't possible in the exam class, is it possible to simply not use the exam commands and create newcommands that can replicate the format I want.

Thanks in advanced.

Answer 1

Try this code with some changes of \qformat and the hooks to make everything left aligned.

The horizontal label separation can be adjusted using \setlength{\iseparation}{<space>} (used 1ex in the example).

Inside the question text you can use \newline to start a new line or \par to start a new paragraph.
