Correção de texto: Differences between my sisters

Hello guys!

May you help me with the text below?
It have something wrong?

I have two sisters, they are called Andresa and Caroline. Andresa is old than me and Caroline is my young sister, I'm the middle brother. With eight years apart they are seem very physically, both are small, have brown curly hair, black eyes and they have thin body. Both have glasses for read and write too.
They are interested for differents subjects, for exemple, my sister Andresa likes watching novel and do exercices but my sister Caroline likes read and study chemical. Yes! She likes the chemical area, she is studing chemical at ETECAP in Campinas. Andresa is gratuated in administration and works in a multionational company. Although they have something in common, they love buy clothes, I'm not.
My sisters are funny but very angry. Bit by bit I'm learned to stay out of the way when they want something, isn't easy being the middle brother because I need to deal with the authority of my older sister and the pampering of my younger sister.


Thanks a lot!
