Introduction:say what you're going to say
Middle: say it
Conclusion: say that you have said it, provide a judgement and add one other point
Here is an excellent presentation on WEESTEPS...
So if you were going to evaluate the London Congestion Charge (nudge, nudge) then you would refer collectively to the evidence you have prsented, make a judgement and then add one further point.
Thus if you had an essay about freight rail (nudge, nudge) then you would look at the usage from the business view, look at the costs, reliability but in the conclusion add the point that not all businesses are profit maximisers. (That's an example of a final point.)
Very important to always keep your eye on the clock too.
