Whether it is necessary to take the IELTS test depends mainly on the students' main weaknesses and whether the learning methods are effective. If you have a good foundation, you can teach yourself for a while and see the effect. If the foundation is weak, you can choose to study in classes.

IELTS learning mainly has the following suggestions for students:

1, generally speaking, vocabulary is very important, so we must ensure that the vocabulary reaches the standard. Reading books and memorizing words may not be very effective. Listening and memorizing words can be combined to strengthen the brain's ability to respond to this word, which is also conducive to the improvement of listening.

2. In listening, choose suitable materials and practice reading and dictation.

3. In reading, vocabulary, grammar and brush questions are combined into one. Grammar is especially important for reading. Poor grammar and incomprehensible long sentences in reading directly affect the quality of doing the questions. Of course, grammar is not only important for reading, but also for listening, speaking and writing.

4. In oral English, accumulate materials and practice according to IELTS speaking machine or other practice materials.

5. In writing, accumulate materials, write more and practice more. Of course, it's best to find a partner or teacher to revise it after writing, compare the model essay, summarize it by yourself and absorb the essence.
