English conversation

I just came back from the English conversation which was from 6 to 7 PM in the library. Today two new people came to join us. They all came from Columbia, one of them speak English very fluently. I hope I can speak well and listen good too, but it seems a very long way to me.

I just came back from my English conversation group which was from 6 to 7PM at the library.  Today two new people came to join us.  They both came from Colombia, and one of them spoke English fluently. I hope one day I will be able to speak and understand well, but it seems a long time from now to me.

You could also use an instead of my in the first sentence.  my personalizes it.

All refers to three or more. both refers to two.

Very is not required as fluently already implies command of the language.

You could also say 'It seems far-off to me' in the last sentence.
