Don't you have a good function to handle stuff like that?

void do_exam(struct university * my_uni)
{
  struct answers a; 
  int errorcode=0;
  push_lazy_me_to_exam(this);
  a=pull_answer_from_pocket(this->pocket);
  errorcode=apply_answers(a, my_uni->examroom->exam);
  if (errorcode)
  {
    use_object(this->knife, my_uni->staff->examinator); 
    return;
  }
  push(my_uni->examroom->exam);
  get_pissed(this, my_uni->bar);
  return;
}
