Ni hao! Wo de Zhongwen hen bu hao.. Wo yao xuesheng  xuexi  henduo zhongwen! Tai hao le!

你好！   我  的  中文         很   不  好...  我   要   学生          学习    很多      中文！       太好了！

1)"我要学习很多中文（wo yao xue xi hen duo zhong wen". As for this sentence..its not wrong,actually,but its really a little weird ;D.Its not widely used here.Instead,we say "我要学习很多关于中文的东西" （I will learn a lot about Chinese.）

3)."学习"：我在学习汉语(I am learning Chinese.)

    "学生"：“我是一名学生”(I am a student.) They are totally different,pay attention to that ;)

2)I think you have just started ;D.Well,my suggestion is that you should try to WRITE Chinese characters.After all,you cannot use "Pinyin(拼音)" all the time ;)

You have done a good job ;D.加油！
