There's no particular format when it comes to a 500 page essay paper. Usually, the assigner provides the format instructions. Otherwise, here are some things that you should be mindful of:
· Keep everything double-spaced. It is a requisite for academic paper writing. It helps improve the readability.
· Times New Roman is the perfect font choice which is highly opted for scientific writing. It is easier to read.
· The font size should be 12 pt since it is not very small.
· Maintain 1” inch margin on all the sides.
If you still struggle, it is best to hire a professional assignment writer online.
