For the following MWE,
\documentclass[addpoints]{exam}
\begin{document}
\setlength{\parindent}{0pt}
\qformat{\textbf{\underline{Question (\thequestion) [\totalpoints\ Marks]}}\hfill}
\begin{questions}
\question[15]
\vspace{\baselineskip}% doesn't increase the spacing between the head and body
question body
\end{questions}
\end{document}
how can I:
1- increase the spacing between the question head and its body (in addition to understanding why vspace doesn't work as expected)
2- and left-align the question body with its head?


\leftmargin,\labelwidthand\labelsep. Or you can refer me that part of the manual where I can find some explanation about them. – Diaa Sep 02 '18 at 21:43questionsenvironment is nothing more than a list, likeitemize. Covered deep in theexamclass,\questionis merely an\item, so the normal list paramaters apply.
