The only inherent difference between BTEC and A-level students is the type of qualification they are doing, although, perhaps, BTEC students may be more passionate about what they're doing, since they're doing something more specific, as they know that they want to do it. Anyway, it's probably just that your college that's full of *****, rather than anything else.
BTEC courses are not inherently easier than A-level courses, many A-level students go to college and only have to attend 2-3 days a week, whilst many BTEC students have to work a full five day week, it all comes down to the courses you choose to do, rather than the type of qualification you choose,especially since most BTEC students opt to do level 3 BTECs which are equivalent to 3 A-levels, so don’t even act like BTEC qualifications are somehow less valuable than A-level qualifications. Plus, before anyone comments that A-levels better prepare you for university, so you’re more likely to get in: BTECs are for people interested in going to work sooner, and are the best way to achieve that (not that it’s impossible to get into a university with a BTEC, many people do). Besides, not everybody wants to go to university, or even a top university, for that matter
Actually, in my opinion, making broad generalisations based on your limited experiences is the truly immature thing to do, and is actually quite disrespectful,especially when you're undermining the hard work of some people (BTEC students).
