English Study in China

Small  Chinese kids children always ask themselves this question, “Why do we learn English?”
We have ask this question because English is useless in our daily life.
Then why shall should we learn English?
Because English is a very important subject in our study curriculum.
Exams exam test our English.
If you wanna want to go to a better school, pass the exams and get your diploma, English is important.
But they never exam test our spoken English…
So our pronunciation is terrible. We have no confidence in our pronunciation.
We learn study English as we learning study Math.
It’s just knowledge, not living a usable skills. (or: not something we can use)
Sorry to say that, but English study makes me feel boring bored and sleepy.
I'm  got tired of it. .
But no one can help us.
Nothing will change it.

Your passage is well written and easy to understand.  I have just a few small comments.

Kids is slang so I used children.  To say small Chinese children is OK but, although we say small children, to use two modifiers before children sounds a little awkward to me.  I don't know why.  So I would just say Chinese children.

An American child would say, Why do I have to study such-and-such?

A curriculum is a course of study.

Exam is the noun.  Examine is the verb.  Test is more commonly used as both a verb and noun.
Study and learn both have roughly the same meaning but not exactly.   Study, 学习, is the process, learn, 学会, is the result.  If you study every day, you'll learn English.

Wanna is internet slang, not a word, and used only in internet chatting.

Although we use feel with many conditions or emotions, we can also use  the verb to be.  I feel sleepy or I am sleepy.  With some words, like bored, we usually say I am bored.  It's just custom.  At least, that's my opinion.  Others may disagree, but I've always heard I'm bored.
I got tired of it is OK.  If I, personally, am bored with sth, I say I'm tired of it.  That's an example of what is "correct but not common,"  that is, something that is grammatically correct but not the way we commonly speak.

Maybe these comments will help.  Maybe not, since you're tired of studying English.  But I figure that if you're on this website practicing English, you must have some interest in it.
