One of my friends graduated from IIM Indore and here are some things about WAT that might be useful to you.
My friend had given the IPM twice, so for IPM WAT 2018 he had the topic on “Violence over Women” and for IPM WAT 2019, he had the topic “Technology”, candidates had to write for or against the motion. Sticking to the topic and giving a valid argument would support your write-up.
