Is there any chance for any average student to get admission in any good B School who dont know how to speak well in english ?

hi,

see you have not mentioned which course you want to pursue, it is bba or mba or pgdm,. in case of mba or pgdm , after the management entrance test result declares, candidates are shortlisted according to their score and academic marks, after than gd or personal interview rounds held. now if you dont have good communication skills, you can not qualify in gd or PI round, in mba course curriculum you are going to learn about different strategies and decision making algorithms, like bachelors courses, there may not be grooming classes. so it is better for you if you start work on your communication and interpersonal skill  when are you preparing for mba admission test. its not difficult to make your communication better, read news paper, read any good english books, practice talking in front of mirror. hope it would help you to over come your difficulty.
