For mi is good to add a line code in WpProQuiz_View_FrontQuiz.php file:

<script type="text/javascript">
		jQuery.noConflict(); //line added
		jQuery(document).ready(function($) {
			$('#wpProQuiz_<?php echo $this->quiz->getId(); ?>').wpProQuizFront({
				quizId: <?php echo (int)$this->quiz->getId(); ?>,
				mode: <?php echo (int)$this->quiz->getQuizModus(); ?>,
				globalPoints: <?php echo (int)$quizData['globalPoints']; ?>,
				timelimit: <?php echo (int)$this->quiz->getTimeLimit(); ?>,
				resultsGrade: <?php echo $resultsProzent; ?>,
				bo: <?php echo $bo ?>,
				qpp: <?php echo $this->quiz->getQuestionsPerPage(); ?>,
				catPoints: <?php echo json_encode($quizData['catPoints']); ?>,
				formPos: <?php echo (int)$this->quiz->getFormShowPosition(); ?>,
				lbn: <?php echo json_encode(($this->quiz->isShowReviewQuestion() && !$this->quiz->isQuizSummaryHide()) ? __('Quiz-summary', 'wp-pro-quiz') : __('Finish quiz', 'wp-pro-quiz')); ?>,
				json: <?php echo json_encode($quizData['json']); ?>
			});
		});
		</script>

The same in line 152 aprox:

<script type="text/javascript">
			jQuery.noConflict();/*line added*/
		jQuery(document).ready(function($) {
			$('#wpProQuiz_<?php echo $this->quiz->getId(); ?>').wpProQuizFront({
				quizId: <?php echo (int)$this->quiz->getId(); ?>,
				mode: <?php echo (int)$this->quiz->getQuizModus(); ?>,
				timelimit: <?php echo (int)$this->quiz->getTimeLimit(); ?>,
				resultsGrade: <?php echo $resultsProzent; ?>,
				bo: <?php echo $bo ?>,
				qpp: <?php echo $this->quiz->getQuestionsPerPage(); ?>,
				formPos: <?php echo (int)$this->quiz->getFormShowPosition(); ?>,
				lbn: <?php echo json_encode(($this->quiz->isShowReviewQuestion() && !$this->quiz->isQuizSummaryHide()) ? __('Quiz-summary', 'wp-pro-quiz') : __('Finish quiz', 'wp-pro-quiz')); ?>
			});
		});
		</script>

Thanks!!
