Try and write new words in sentences that are personalised to you.

For example, if the new word is 'superb'

'My favourite film is Batman, it is superb'

"I made a superb pizza yesterday"

"I'm looking forward to the party, it's going to be superb!"

There are also flashcard style programmes, such as 'ANKI', which can help you remember words.

go around your city get objects and things you see on your day inside your house etc.... put down on a notebook. everything you you see and you do not know the translation. in your own native language. when home google the word. then write down on the side( or on the sheet down the one you writing so you can compare it everytime you wish) of that word you got in english. do it whenever you can. you will grow your  vocabulary fast.
