Section 4 is the most difficult part of the listening test for the following reasons:
- There is no break in the middle of the 10 questions
- You hear one speaker giving a fairly long talk or lecture
- The speaker will speak quite quickly
- A wider range of vocabulary is used, compared to the other sections
Here's my tip: Don't worry too much about this section. Try to get as many points from the other 3 sections as you can, and this will allow you to lose points in section 4. Remember that you can make 10 mistakes and still get a band 7.
