Quiz module question

Hi, I have a hopefully easy question. I'm familair with php but am new to drupal but I think this will be an easy one.
We are planning to use the quiz module, http://drupal.org/project/modules?text=quiz on our website and have a contest with it. We need to tie the quiz scores into another system (we are a non-profit and we have to tie our activities in with Democracy in Action, they're web tools designed for non-profits that we use extensively). I was looking at the quiz.module file and found these lines of code:

function quiz_quiz_finished($quiz, $score, $rid) {
global $user;
// function to export results to grade book will be added later
// function to export result in pdf, XML, CVS format
// function to display results visually

//function to send results over email
if ($user->uid && variable_get('quiz_email_results', 1) && variable_get('quiz_use_passfail', 1)) { // email can be sent only for registered users
drupal_mail('quiz', 'notice', $user->mail, NULL, array($quiz, $score, $rid));
drupal_set_message(t('Results has been sent to your e-mail ID.'));
}

My question is, if I get rid of all this code and simply put in something like this

$URL="http://www.example.com/$aDIAPageToReadScore=$ScoreOfQuiz";

header ("Location: $URL");

Will this break the module? I am fairly confident it won't but I am not familiar enough with the module or drupal yet to know for sure. Also if I'm approaching this the wrong way let me know, I'm always open to doing things easier and the right way ;)

Thanks in advance for any help or suggestions.
