The way to increase your accuracy % when taking tests is to actually increase your level. And to increase your level, you need to stop to learn new knowledge you didn't know with every question you do. Doing lots of practice questions by itself won't help you learn much if you don't take the time after each question to study.

If you can slow down to "diagnose" your illness and spend time developing it through the many programs available at TAMN, you will be able to achieve the TOEIC score you want as quickly as possible.

Listen again, compare with the transcript, see what words you don't hear, and what's the reason? Is it because I know the words but don't know how to pronounce them, leading to not being able to understand them? Or is the reflex to understand words still too slow? Or is it completely inaudible because you don't know the word?...

Read the transcript and the translation to really understand the content of the lesson and take notes on the phrases/vocabulary you want to learn.

Listen to the transcript a few more times until you hear the whole passage clearly, especially the places that you couldn't hear at first.

Listen 1-2 more times without looking at the transcript.

If you have time, imitate the reading exactly according to the listening text.
