OLQ is nothing but the way a candidate should behave , react or respond in difficult as well as daily situations . These are not developed within a day , a week or a month, but how you are able to grasp and adopt / implement in real life it matters. It depends on the habits that you follow , so change your habits and convert them according to become an officer.
If you know yourself and the points where you need to improve you can very well remain an officer, even before joining the academy .
