management: doing this, you should combine it with a more specific major like say accounting, marketing etc. In management you learn to be like a business consultant, gaining knowledge about organisational aspects like structure, behaviour and stuff but you wouldn't be able to get a job in management withthe degree. You need experience and thats why you would need to combine it with another major/sub-major.
It a good course if you like it, and it is more suited to the english-type person (as in the subject not the people) and only has accounting as the maths subject. But choose what you like, although you may think you suck at math, you can get alot of support from the uni [unless LSU is gone] with maths and the mathematics isnt that hard as say 2 unit at high school. Trust me, there is no differentiation and intergration and all that other bs [i did 2u as well]. Stats is easy peasy if you read the text and remeber how the formulas work and what they mean. Accounting is passable if you read the book and do the work. first year subjects are a bit more book related than 2nd and 3rd year subjects where there is more brain power needed.
