People often ask me why I put the overview (summary) after the introduction instead of at the end of my task 1 reports.
I tell my students that they can choose where to put the overview. It's fine to put it after the introduction, and it's fine to put it at the end - your score will be the same either way.
However, there are 2 reasons why I personally prefer to put the overview after the introduction, rather than at the end:
- I find it easier and more logical to begin with the general information and main features before I describe specific details.
- The overview is very important, so I think we should prioritise it. If you want a high score, your overview / summary needs to be good, not something that you write in a hurry when your time is running out.
