I am from Iraq and I am studying English. How do I develop English?

One of my biggest tips is to learn conjugates to important words used in every day language. For example they, there, their and past tense verbs like was and did.

To improve your English it is recommendable to make the learning process your new hobby!

There are hundreds of websites where you can practice and clear doubts you may find every day, conversation clubs, etc.

Try to take advantage of your everyday activities to practice: if you like watching movies, do it in English; if you like listening to music, reading books, try to do it in English. Do whatever you like to do in the language and you'll see how fast you improve.
