goto ap-admin - all pages - page
and change the title of drive page and event page check if it does the trick.
if it does not work then
add this code in wp-admin -- wplms -- footer --- google analytics code.
<script>
jQuery(document).ready(function($){
$('.single-course div#item-nav li#drive a').text('drive hai new wala');
$('.single-course div#item-nav li#events a').text('event hai new wala');
