Hi Jagath!

I've heard that a great way to begin learning a new language is to go about it the same way you began learning your native language: start at the beginning. Many instructors suggest reading children's books or doing grade-school level exercises in the language you are learning, because you are starting at the same level as a young student would be. Lucky for you, this site has tons of worksheets that can help you learn English this way! I've added a link below to start you off.

Hope this helps!
