There are so many ways to improve your English skill...however, my advice for you for that is "not worry about it too much". First of all, you need to be relaxed about it. If you feel the pressure from making mistakes in grammer in English, you tend to make more mistakes. Also, it's very important to know your level of English. Step by step, you can bring up your level...."taking time" to achieve next level,not jump onto the level you are not yet prepared. If you concentrate on only in grammer...most likely you get tired of this language . It's good to have a balance. Have a conversation in English for improving speaking in English. Read some books to learn new vocabulary. Write some letters to someone who can respond in English etc... they are also very important for achieving the level you want to reach. If you need a referance book, I can highly recommend "CAMBRIDGE university press: Grammer in Use" Hope my message gives you a bit of help. Best of luck!

Dear Quynh Vy, first of all you should reflect about which learning method it's suitable for you. For example, I learn better watching videos and taking notes down, if you also like to it a good idea is to look up some YouTube videos and channels (there are lots of them) to learn the specific topics you need. Bellow are some links to help you start: http://www.youtube.com/user/JenniferESL http://www.youtube.com/user/bizpod http://www.youtube.com/user/englishlessons4u

With more practice :P

Aside from these other answers, it's also nice to read many books. (novels and such) You can learn grammar, new vocabulary, and at the same time enjoy a good story. =P
