Hello Dharani answering your question, sadly you have scored very less marks\ percentage in your academics. For getting into a top IIM college you need to have a very appreciable score which is basically more than 90% .

Getting into IIM is not an easy task you have to work hard since the very beginning. For getting into IIM you will have to score high in the entrance exam of IIM which is Common Entrance Test. I wish you all the luck.
