Shagufa I assume you are talking about micro presentation in the BBA selection procedure of Christ University. 

I am sharing a PDF link with you which has 75 topics on which you need to make a micro presentation and you will be asked to pick a topic on the random basis at the Selection Process Venue and present orally on the Topic for 90 seconds. You will only get one topic there will be no second chance.

Misrepresentation is basically a test to analyse a management aspirant’s writing skills and coherency & clarity of thought process. So, make sure you write atleast a page for each topic which is worth speaking for 90 seconds and sums up all the major points about the topic.

Feel free to ask if you have any more queries. All the best!!
