Hello Nubia,
I gonna tell you simple ways to learn English quickly...
* first thing :you have to love the language you learn (English).
*Know more about (English as a language -culture- people-..so on)
* try to know more vocabularies and note down..every day revise and use in your daily life.
* second step:start to study grammar ..also revise every day and try to test your grammar skills through grammar exercises.
* after that you can support that with reading novels and stories...listening songs..watching movies... speak with friends ..
tryyy and you will see how your skills will go better...
