Need help!

[csak1162]

Hello,
I am from Austria and I am twentytwo years old. I was quite good at English in school, but that was four years ago. Since that time I haven't written English. I study Maths at University, but I want to become an English and Maths teacher now. But I am not sure if I am good enough in English, so I started watching movies and TV shows in English and learned some vocabulary and revised some grammar chapters, but I don't know if that is enough. So I would be pleased for any piece of advice.

Please correct my text!
