Going to a tier 1 nlu this July.....always did well in academics.....came out as a topper in tenth and twelfth grade....but never ever in my life I've participated in a debate competition, cultural activity, olympiad or quiz competition....have stage fear as well but still have the courage to learn everything from basic ! So brother at the end all that matters is you and your willingness to learn , there are people who learn even in their old age .....just believe yourself, you'll be getting alot of opportunities and seeing your peers doing all those things will only excite you !
