Lots of candidates find the last part of the speaking test the hardest of all three.It is mainly because in the final part of the test they have to answer abstract questions.Unlike the previous segments of the test,the question are not about the life of the candidate.The candidates need to be knowledgeable about the topics that come up during the discussion.One useful technique to make sure that the answer comes full circle is to personalise it.Look at the example below.

Do you think that it is a good idea for students to live on campus?

Absolutely.Living on campus allows students to concentrate on their studies better.In my case,when I was in college,for the whole length of the course I lived on campus.It helped me to spend enough time studying for my course and it also presented me the opportunity to join study groups as there were many other students from my class living in college accommodation.So,I think it is a good idea for students to live on campus if they are from a faraway town or village.
