Hi Anna,
How are you? I hope that your mother feel better now. Sorry that I haven't written to you for such a long time but I haven't had a time since two weeks!
Last month, you wrote to me that you can't learn effectively. I have some advices for you.
First, you have to focus on your homework. Don't listen to music or watch TV when you are learning.
You should also drink much water, because it's good fot our brain. Try to avoid drinks like coca-cola or sprite.
You can't learn too much. Make an hour break for every two hours.
You shouldn't learn when you're tired, the best time for learning is morning. Your brain is rested.
Please, try to comply with my instructions.
