I'm trying to improve my listening with series, movies etc.

For the past few Last days I have been trying to improve my listening comprehension by watching movies, series and documentaries with audio in english. I think it's a good way to understand quickly and it works a lot to very well for me.

I decided to write this small text to practice ways to use "have been". I don't know if I'm doing it correctly, but I'm really trying.

I have been studying english very much, because I want to get fluency asap!

therefore, now is your time. Now it's your turn. Help me with my text and show me all the mistakes that I made.

Thanks everyone!
