Help For Course At Uni

hello nairalanders. i really need your help. i am in the UK and planning to go to uni. i have applied already to study maths at uni, but I'm thinking of changing to a course that will make me get a very good job in Nigeria , as i am thinking of going back home after my studies. i would really appreciate any suggestions , by the way, what do you all think of economics as a course for Nigeria's job market. thanks a lot
