I am 4th year economics student and What i suggest you get ready to tackle calculus and algebra alot everything you gone learn is related to maths so just look up to your 11 and 12 maths then you will be fine and job opportunity you could do almost everything related to business like you can do accountant job,marketing lots of thing so don't worry also if you want your own business it will aid in building it but you just have to have entrepreneur mindset and determination that is all u need
