I guess people really look up to BSA people mainly because they're the survivors of the difficult challenges that were thrown upon them. A 2.0 average, a couple of CEL exams, difficult accounting questions. Not to mention, BSA peeps usually top the exams.
Your course doesn't label you. It does not define who you are. I have friends (yihee. :">) who topped the recent departmental exams even if they're BSAcT students; they were even scoring higher than my blockmates in Block A including quizbowlers. To be honest, some BSA students aren't even that smart. I know BSAcT students who are smarter naturally. It's just that some of these BSA peeps love to study 24/7 and thus with ample time, mastered whatever it is they needed to master.
Stop feeling insecure though because it just clouds your mind. Put bluntly, if you're dumb, you're gonna be 5x dumber if you're too insecure. I think what's wrong about society is that sometimes, we're too busy competing with other people that we tend to forget that the first person we should be competing with is ourselves specifically on how to be better than what we are now, and how to make up for our flaws.
Just because you stumbled, doesn't mean you've lost your way. ;)
