It seems most of people like to ask others about how to learn the language well ,maybe it is the short cut to grasp the language well because it concentrates a lot of learning experiences of others .But I have my own views .if a person always asks other people about their learning method but lazy to find the way which is suitable himself ,he also cannot make a big progress in his learning .It just like a person who just wants to ask other else how the taste the food but actually he dare not to do it by himself ,he fears to taste the bad food which can let him feel uncomfortable even out of stomach .but please consider it most ,only you have a try ,although it is full of arduous ,but you can learn more in the process and find the best learning way for your self . Best wishes .

Yes ,it is a good question for people who want to study english well ,including me .But I point out that it is not the simple thing to learn your grammar well , you should practise it everyday when you got your new knowledge .Sure ,the best way for you is to communicate with the native-speaker ,and they are willing to help you to correct your mistakes in your sentences .That is a way which can improve your learning quickly and get much more knowledge than you only learning from the book or by yourself .
