PART 1
The first thing you're assessed on is your content. That basically means reading the task carefully and doing what you are told to do! In part 1 you are given three bullet points but are asked to talk about TWO of them. (You're also given some opinions on the topic that you can use if you want, but you don't have to.) Here's an example of the three bullet points and a task:
If I were planning my answer, I'd probably choose 'giving rules' and 'setting an example' as my two points because I feel like I have more to say about those topics. (How much would I write about 'offering advice'? Nothing! Because I should only write about two things!)
Another important point is to say which is more effective. I'd probably write one paragraph about 'giving rules', and the next paragraph would be about 'setting an example' - I would be sure to give reasons why it was a more effective way to influence younger people.
