Hi
Try reading the newspapers & other publication , it will help u learn how the sentences are generally constructed.
Use dictionary to identify new words.meanings & pronunciation
Buy Wren & Martin , its an excellent book on grammar.
Identify a friend/close colleague who wont make fun of you and has great english - speak with them in english only , & ask them to correct you when you are wrong.
All the best.
Don't worry , you will learn it...
