What gcse's do you need to go into business and finace?
you need aqa levels as well as this you need to be good at your main lessons such as maths,english and also science but science is good because if you wish to be a midwife ,doctors hospatility etc it very good for you also you need qualication and need to have al least some gcse done otherwise you wouldnt be able to be anything like for example if you want to open you own and new business you need alot of maths .
