The former is to understand and recite words, and the latter is to analyze the sentence structure or grammar that is your biggest headache. If you are listening, you should listen to more words and sentences.

A score of 5.5 in Class G is not high, and it may take a long time for people with poor foundation. Oral English and composition are common weaknesses of China people, so I suggest you find a foreigner to practice your oral English first. If you can't find a foreigner, just download a video online and learn pronunciation from others. Record it yourself, practice it yourself. Finally, composition, this item also needs to buy textbooks, because writing skills depend on the application of words and phrases and the composition of sentences.

As for the recommended books, IELTS vocabulary books: Yu Hongmin and words can be classified and recorded, or because of the cost, you can go directly to the online dictionary cutting software and choose IELTS vocabulary yourself, which is more economical. Other books are really unnecessary for IELTS 5.5.
