I concur. b,c.

First notebook entry: Introducing myself

I'm learning <strike>e</strike>English because <strike>i</strike>I study (more common to say "I am studying", but "I study" is correct as well) <strike>i</strike>Information <strike>s</strike>Science and <strike>i</strike>I think it is very important for my future career to know how to write and speak in <strike>e</strike>English. I hope to meet somebody to improve my <strike>e</strike>English and <strike>i</strike>I hope to teach <strike>his</strike> him or her Spanish if he or she wants.

Thank you¡¡ !! :P

Not bad :)

First notebook entry: my name is alexander and <strike>i</strike> I live in bogota colombia

hi, <strike>i</strike>I´m studying english and <strike>i</strike> I would like to improve my skills in this language and <strike>practicing </strike>practice <strike>my</strike> speaking

You could also say, "I'm studying English and I would like to improve my skills in this language by practicing (my) speaking."  Or simply "I need (or I would like to) practice speaking

Very good, though! :)

When in doubt, just say "I have"-- "I have got" is repetitive, unnecessary, and I ddoooon't think it's actually grammatically correct...I COULD be wrong on that, though. But "I've got" is very commonly used in informal conversation. "I have GOT" can also be used for emphasis though, as Eliot used in the sentence "I've got to leave," often you'll hear someone say "I have GOT to leave now." Another example, in Batman Begins when Batman goes wooshing by in his tankmobile, Gordon says "I('ve) gotta get me one of those..." Hope that wasn't more confusing than it was helpful :)

Yeah, he's right, it should be "fool's errand" because it's possessive. Even native speakers make mistakes sometimes, but good job catching that ;) "I have been reading CNN News, and they quoted someone as saying "a fools errand," but my dictionary entry says "a fool's errend." Why is the apostrophe dropped here?" Hope that helps :)
