For the references you need to cite you can use the usual “author-date system”:
1- place the authors name and the year of the publication within brackets in the text
2- at the end of the text put the reference list, ordered alphabetically
All applicants go through a series of tests that check their level of English and knowledge of formatting styles. The applicant is also required to present a sample of writing to the Evaluation Department. If you wish to find out more about the procedure, check out the whole process.
