say sth about major

Before in China. my major is accounting.Everyone say this major is good. I know.If I study well.I will help my father.because my father is chartered accountant.But I don't like.maybe, I am very careless..
In my college,My computer is the best in the class. well. I am interest in computer.when I have exam.=,I feel very very easy..so, I change my major in Singapore.
I change my major that my relative are disappointed.but my parents say if you like you can choose. Whatever I choose.I can do my best in it...
in chinglish.."good good study .day day up" ^_^
