I've been feeling very bad these days because I failed another English test. I tried my best, but I still
couldn't get good grades. It's hard for me to memorize English words and I have a lot of difficulties with
the grammar. Since I am a little shy, I am afraid of speaking English in class. I know studying English well
is very important, so I don't want to stop studying it. How do you study English? Can you give me some
advice?
