I will go to New Zealand in one month, but what if my English is super poor?

Apply for a language school after going there. The language school is divided into six classes, starting with 1 class, and there are several exams every week. After that, you can go to Class 2 ... That's it. Class 6 can almost take the IELTS test, but there is no difference between domestic and foreign IELTS tests, which is much more expensive, so if you don't know English, you should report to domestic professional English classes, small classes or one-on-one tutoring. The effect is very good, the price is about 1 10,000, and the cost performance is very high. Wall Street, EF and so on, if English is ok, sign up for a professional class like Global IELTS, which specializes in IELTS, and the price is lower.
