Your friend has enough money to buy either a smartphone or laptop, but not both what would you recommend him & why?

You don't need to take notes for Q1/Q2; Taking notes for Q3/Q4/Q5/Q6.

You only need to keep a 'big map' in mind:

first 1-2 sentences: introduction. my opinion: A or B. agree or disagree. about 5-10 seconds

First, reason 1 (1 sentence) + why reason 1 (some arguments. 1-2 sentence) + a small conclusion for reason 1(like advantages of reason 1 or comparisons if not reason 1, 1-2 sentence). // about 15 seconds

Second, reason 2 (1 sentence) + why reason 2 (some arguments. 1-2 sentence) + a small conclusion for reason 2(like advantages of reason 2 or comparisons if not reason 2, 1-2 sentence). // about 15 seconds

Conclusion: Don't need a conclusion. (you can have one only when you don't have something to talk about)

If you are running out of thoughts. You can apply 'save time', 'save money', 'find a job', 'make friends', 'get more information' as reasons to all speaking topics.
