I do think that colleges aren't always honest about these stuff. Btecs are risky. Same with functional skills because despite what tutors say, they just aren't seen as equal by universities. Also they largely restrict what higher education courses you can go for.
The only time I would say a btec is good is if you know exactly what you want to do as a career and if you want to study for a "vocational career". By that I mean a career you need to be trained for. In my opinion business is not a vocational subject. You can learn it by researching on the internet and then start small. One thing I've noticed is that a lot of people do business at uni and college because they have no idea what they actually want to do in the future. They want to own a business yet there are so many opportunities to start small nowadays especially with the internet. But they go through school then college then uni then get upset when they can't find a job in their chosen field because they were lied to and told that they will do okay.
I'm not saying that business isn't a good subject but you really need to think about the security of your future! We don't know when the next reccession may hit so you need to think if what your studying will actually get you a decent income and if the job will always be in demand.
One thing I've learnt is that colleges do lie to try and fill up spaces on their courses. For your own good if you are going to do a btec please do it in a subject that will actually benefit you.
