You may or may not want to read this as i'd imagine as Im studying in the UK the course might be slightly different.
Anyway I've just finished my first year of my Business degree and thoroughly enjoyed it.
We've studied a broad range of topics to do with the "business world" so far, including Economics (which i found particularly interesting due to the current climate), Finance, Statistics, IT, Management (this involved quite a bit of psychology like finding out how people are motivated, leadership styles etc which i also found fascinating).
Next year i'm specifying more into entrepreneurialship. This will allow me to learn more about how to set up my own business in the future, which is something i've thought about in the past. But even if i dont, i should still to move into a slightly different career path like in the areas stated previously, as i'll hopefully have a fairly good knowledge of those fields by the time i've finished.
Either way it allows me to keep my options open after uni.
My advice is, if you havent already done it, identify the different modules you'd be studying especially in your first year. Also, if you can, try and find out how the modules are weighted with coursework, presentations and exams etc
Just reading your post you might be interested in Business Management if your college does it as that would probably have quite a bit of psychology (but more in a business setting).
Also, from my last year, i only did one marked group presentation. I dont like doing them but if i rehearse well and know what to say when, as well as knowing what everybodyelse is saying etc, without disrupting the "flow" of it much then im usually okay with it personally.
