The goal of this repo to to share update on correct exam latex template
By design, this class sets the fboxsep length to 0, which removes the inner spacing inside an fbox.
Not only does this affects the \fbox command, but this also affects all packages that rely on fboxes to draw frames.
For example, the minted package provides a frame option which underneath relies on fbox to display lines or boxes around a code listing.
Fortunately, minted provides a framesep option which can be used to explicitly increase the spacing, and therefore "fix" (or compensate) the problem explained above:
\setminted{frame=lines,framesep=5pt}
