First notebook entry: Introducing myself

I want [to] learn English. Although I study it in my school life, I feel [that] my English is poor, and can't [fully]  understand many documents writt[en] in [E]nglish, so I need your help. I'm Chinese, I can help you to improve your Chinese and other things about Chinese and Chinese culture!

Notes: if you are still going to school, you would say "I study it in school"

          if you have finished school, you would say "I studied it at  school"

          Remember capitals for "I" when referring to yourself.
