What are the factors that affect the passing rate of the board exam?

Hangout ,revision ,insincerity , focus, sleep, attitude, time management are the main things. According to me if one wants to pass out with good marks he needs to plunge into studies right from day 1. But thats not all.. revision is something that is needed the most. We should revise one lesson atleast 3to4 times in order to make it on the tip of the mind. Avoid excessive hangout And plan the time well. Think bigger and better and prove that you are the best .
