Is it hard to study English? I don't think so.

Listening to your teacher and your friends in the class is very important. Plus making some notes will be very helpful, too.
Read your notes and try to remember the lesson when you get home.
Revise the words, make a couple of questions,
negative and affirmative sentences,
act the story in your book.
Share what you learned with your family.
It will only take 15-20 minutes. Try once,
you will be addicted to it:)
