1. Define your topic premises so you can structure your essay
around it.
2. Go in depth. Don't just say "Raising bus fares are bad because
economy in recession, and they already raised it 3 times in last 5
years". List examples, Statistics, historical evidence, compare
situations.
Which means - research.<
3. Quote famous people.
4. Plan your essays. Got good points, no plan also no use. What's
your premise? How far do your points support your premise? What
points goes against your premise?
5. Round it up
Basically writing GP is like writing out a debate strategy. It
isn't just a matter of illustrating points. Imagine you are on a
debating team and given that topic. Every point you give may be
debunked by your opponent (who incidently is also you), how would
your opponent give the other side of the story? How can you
convince your audience that your conclusion is the one that makes
the most sense?
