Could I say this?

[JuanKB]

Hi, I'm a english student from Spain. I have a doubt and I'll want you to answer me it, please.

In an english exam at school there was an exercise in which you have to correct the mistakes.

In a sentence I corrected:

- I don't often go to the cinema.

The teacher deducts me 0,8 points (above 10).

Is this correct? If it is not, It's an important mistake?

Thank you very much

That sentence is fine.

That sentence is fine.

And in case you were wondering, it's fine in British English too.

Thank you so much for you aswers. I knew it's well . I'm wondering why I got a 9,2 (above 10) without any mistake. I asked my teacher about the reason and she said it was that sentence.

Now I know it's not.

One more thing, please.

In a formal letter, what more endings could I use? (except of "sincerely" and "yours faithfully")

I often use "Sincerely yours".
