So Prakash !!
The first and foremost thing for you to do now is to INTROSPECT
By that I mean , you really need to think about yourself - on what would you wish to be / How do you want to see yourself in 4-5 years from now
With that your major part of preparation for an MBA application is done ; after that you try to answer yourself , why do you want an MBA ? and doing an MBA will give you what ?
After undergoing this process , you will realize you still need to do a lot more to map for the requirements that you need to get an ADMIT
It is this "lot more" , which will help you to the aligned extra curriculars , Now every part of the step you do to solidify this "lot more" will be your extra curriculars
I need not explain you how for the above explanation , all this stuff which you do will not only help you in writing the essays but also to stay confident in answering the qsns to the panel

Consider Kudos , if this helped
All the very Best !!
