How to make a clear essay layout in LaTex?

There is an Overleaf Example file to store all the example coding, you can open it while reading this LaTeX guideline.

Cover Page

There is no standard format for a cover page; you can have a title, research question, subject and word count. The research question,  subject and word count are required on the cover page, while the title is optional. For fair and equitable IB assessments, please do not mention your name, school and candidate number in EE.

Bibliography 

As the reference information needs to be kept separately, you should create a new file in the same project. (The new file button of Overleaf is on the second row of the left top corner.) Moreover, the file name must end with “.bib” (ref.bib will be used as the example).

If you use Google Scholar to do the research, you can just click the “Cite” button and then click the “BibTeX” button for getting the bibliography format that can be directly used in Latex. The label “resnik2012denationalization” is assigned to this entry, is a unique identifier that can be used to refer this article within the document.

Like this:

@article{resnik2012denationalization,   title={The denationalization of education and the expansion of the International Baccalaureate},   author={Resnik, Julia},   journal={Comparative Education Review},   volume={56},   number={2},   pages={248–269},   year={2012},   publisher={University of Chicago Press Chicago, IL} }

Otherwise, you can follow the example to enter the required information.
