Some of the listening questions can be tricky! The best thing to do is to practice at home. Find a playlist of classical music on spotify or youtube and put it on shuffle. Then try and write down as much as you can identify on paper during 1 minute of each piece. Once you have practiced this for while, reduce the time to 30 seconds, then 20 seconds then 10 seconds. If you can still identify at least 3 things in each piece in 10 seconds, you're on the right track!
