English learning should be carried out in the following order:

English learning is divided into two parts, one is the establishment of grammar and thinking core, which is called English processor and engine; The second is vocabulary and listening, speaking, reading and writing skills. There are only two, and without two, one becomes a cook without rice. But with grammar and thinking core, you can learn English completely independently, because with powerful English grammar and thinking processor, you can watch American TV shows, English news and English books independently. There are no obstacles in grammar and thinking, that is to say, there are no obstacles in your reading and writing, and the rest is nothing more than increasing the number of words and training in listening, speaking, reading and writing. This can be achieved by watching American TV plays to learn vocabulary and practicing listening and speaking efficiently.

Many English training schools are mixed, and most of them are time-consuming. It is difficult for English learners to choose and judge, and the fees are high. Choosing the wrong ones is a waste of money and time, which hurts their interest in learning English.

Regarding the establishment of English grammar and thinking core, there are better courses on the Internet, such as Principles of English Grammar and Building a Perfect English System in Ten Classes by Baidu. If you read a book, I recommend English Thinking: Deciphering the Principles of English Grammar.
