Hello Satyam 

You haven't mentioned the exam name in which you scored 156 marks and neither you mentioned category which plays an important role . I think it's your jee mains score since you mentioned engineering. If it's so then use jee main college predictor tool to know the colleges you can expect with your rank

If it's the score of some other exam please clearify it in your question. 

Hope it helps you.
