Which one should I choose?
English is vocabulary, grammar, oral English and listening. I want to solve the first problem. No cram school or tutor can help much. You'd better buy a dictionary and work hard. Some dictionaries are very good, with vivid memories and so on. I suggest you buy one. Regarding the third and fourth items, I think you'd better listen to Crazy English more. Good. I didn't say that. At present, the spoken English of most people in China is not very standard, including English majors and even professors. Regarding the second item, I personally think that it is not only cost-effective for you to find a tutor, but he only teaches you one, which is very targeted. For students who can be admitted to Liaoning University, tutoring you should not be a problem. I suggest you find a freshman. Besides, you can ask your parents to help you find a place to find a tutor. College students usually find tutors near schools and city squares.
