Good preparation and planning gives you a clear overview of your material so you can see the best way to organise your points.
Remember that all referencing, in your in-text quotes and your reference list and/or bibliography, must be in the referencing style required by your school, college or university.
These are very different but employ two basic styles: You need to find out precisely which style is adopted by your academic institution and adhere to it strictly as the structure and formatting of the reference differs from type to type.
Knowing how all of your information and points connect will lead to more investment from your reader!
A good essay plan makes the most of your essay material by helping you to organise the content of the essay before you begin writing.
