Low english grades at school

Well, I had two english tests in my school and on both I had got bad grades. I have learned english thought through games, music and youtube videos so I don't really paid attention to rules and gramatical stuff (it can soud sounds strange but I don't haven't even really memorized the weekdays). I also never had taken an eEnglish course, which is very common in my country and most people use this them to learn english. But what I think is that we can learn eanything from the internet if we have enough will. After those bad grades in such a easy language in comparison to the pPortuguese language (my mother language), I'll try to improve my english these days from now on.

Wow! I'm really impressed you've learnt english without a formal course :0

I've corrected you a little harshly when it comes to grammar as I am treating this entry like a formal piece of work. Things like "i" aren't wrong when your messaging a friend or something like that. (I totally use "i" and don't use apostrophes (like the ' in don't) in relaxed settings as well) 

Also I noticed that you said "a english". When a word begins with a vowel (a e i o u), we don't say "a apple" we say "an apple". This is most likely because it's hard for us to say two separate vowel sounds in a row, so we <em>sometimes</em> to put a consonant (any sound that isn't a vowel) between them. 

Please watch your capitalisation of proper nouns like "English" and "Portuguese", we give them capital letters to say "Hey! Look I'm important!". I can't explain the rule really well, but it comes down to; if it's the name of a person or place, give it a capital letter.  

As far as the weekdays go, I learnt Japanese weekdays by writing my schedule with them. Since you see it every day it's quite effective. :P

If you have any questions at all, please don't hesitate to ask me! :D
