modifying a prebuilt module - advice on how to modify a module

HI,

I'm pretty much stuck here. I'm looking at this module and i'm looking at one file and another, but i'm still lost.

I'm new to Drupal but not programming.

But this is a grade up for me compared to the smaller projects i've worked on.

I'm looking at the Quiz module but having a hard time figuring how to go about modifying it to my liking.

Any tips or hints on how to wrap my head around it.
