Boards don't make you linguist nor can help you become one by force or special help. I have seen many linguist in both Indian or quite many foreign language including English whose student life clearly expressed their passion and opting for more than classwork sort of things. Yes, ICSE has a great pattern to feed your passion but then you need to work more honestly. So, best wishes from my end. :)

TEFL graduate course is the best option if you want to make your profile look good and earn more money because the rating of this course is high and most people recommend you this course only.
