To write a good composition, you must understand the given topic or story line. Read several times and see that you understand it and then decide on what to write. This is done by writing a plan of what you want to write. Example, If the title is ‘A mango tree,’ the following questions can assist you:
What is a mango tree?
What does it look like?
Where does it grow?
How useful is it to us?
You can finally summarise with a comment. The purpose of creating a plan is to help in the flow of your composition.
