How to become more smart and good thinkable?

How did I become good at English? 10 Points!!!?

• At one time in my life,I could hardly read an English word.My teachers,class mates and even friends used to laugh at me a lot.But I don't know how,out of nowhere,suddenly what happened,I now can read and speak English faster then most people.My teachers become very impressed.I have never read an English novel or book to imrpove my reading.When I play video games,I unintentionally memorize the cutsecnes and with the style they speal word,I then can speak exactly like them and use their accents in my real life. While my elder brother plays more video games,watches more movies,in fact I don't ever watch movies and my brother has a lot of experience then I do,my English is still a lot better then him. It looks as though my brain forces itself to memorize cutsecnes,words,dialogues,etc.I understood higher level of grammer all on my own,unintentionally.My teachers don't let me explain in English because I would explain with such accent that my mates wouldn't understand. I have never gone to an English speaking country,nor have ever met an English speaking person.I sometimes feel like English language got handed to me.I didn't put any effort at all whatsoever for it.My mom says I have an exceptional brain and I'm smart.I don't believe her.If I were smart,I would at least be one of the best students in my class,which,I am not.I'm one of the lowest in my class. I live in Saudi Arabia.I live in one small house for the past 17 years, I'm now 19. How did I become good at English? Can anyone explain? Good answers are highly appreciated!! Thank You!!!

• Answer:

  Your punctuation is good. Maybe you was an english speaking person in your past life. The more you read the better you become
