Part Three actually contains a wide number of different topics and questions. It would be almost impossible to memorize answers in Part Three.
The best strategy for Part Three is to ignore the actual topic and question and focus on the "language function" of Part Three questions.
These language functions require specific grammar aspects, so for this reason, most of our Part Three responses will be based on grammar.
Look at the following question:
Are houses nowadays the same as houses 50 years ago in your country?
With all Part Three questions it is a good idea to ask the following question:
Why is the examiner asking me this question?
With this example the answer should be:
The examiner is testing my ability to demonstrate my ability to compare two things.
This will be our first question type.
