Hi manliz
I understand what you're trying to say here. Overall your letter does have structure - you have an opening, a middle and a closing section. Is your friend called Fer? In that case, you should address your letter to Fer.Dear Fer,
I actually really like what you've written and grammatically it's nearly there. With the most minimal of tidy-ups, I put this, being careful to use your words:We have been studying English for almost 6 weeks now. I think you have learned a lot because you have the will that makes it possible to learn faster. Now we can use all the words you have learned and have a conversation.
And remember that when you are writing a letter you should always finish it appropriately. As Fer is your friend, you should use:Yours sincerely,
I hope this has helped in some way. If I can help anymore, please do send a message.
Daniel
