[求助] about listening

Damn it~

I am not sure if anyone here has the same feeling on the listening section of Barron. The passages are all very much long (more than 6 mins?) and the lectures are too difficult for me to understand, while maybe the conversations are easier to catch the main ideas.

Will someone share your ways for preparation for listening section? Are there any skills? Actually, it was noted that we should try to take notes during listening, and maybe use some unique marks. However, the problem is what should be written down. Of course, it is impossible to copy down everything, but how to distinguish the important information from the whole passage, especially when you have not seen the questions?
