Wasting time

Well, I'm from Perú and it's too late here and to be honest I do not really know what to write. Anyway, I wanna meet British and American people for practicing this language. I study at the Britanico centre and now I'm at intermediate 12, the next tuesday is gonna be my final exam which means I need to prepare myself.
What do you guys think about this  my writing?

very good , but I think it is better to write "want to " instead of "wanna" 

wanna is not a word, it is slang. 

Wasting time

Well, I'm from Perú and it's too* very late here and to be honest I do not really know what to write. Anyway, I wanna want to** meet bBritish and aAmerican people for practicing this language.

What do you guys think about this writing?

*To describe *really* late in the evening, you use "very" or "quite" or "rather"

**Don't EVER use wanna or gonna in proper written English, they're slang and never acceptable.

Honestly, I think the writing is a bit sloppy for intermediate level and I think you need to review the rules on capitalization, sentence struture, and excise bad habits such as using slang to sound more "native".
