Correção de texto: "I worked in TV Journal..."

Eu escrevi esse texto e gostaria que eu alguém me dissesse se está tudo certo em concordância:

“I worked in TV Journal at the beginning of college. In the third year of college I had to leave it to work in my field, but I did not like. I wanted to return to work with TV newspapers so I need to finish the business school and study communication.”
