Yes, all tutors are familiar with the three most common referencing styles (MLA, APA, and Chicago). If a tutor notices an error in the student’s citations, they will inform them in a comment. For example, “It looks like you are using MLA formatting for your essay! Remember that for in-text citations, you should follow the format (Author last name page number), for example (Smith 47).”
Tutors will also check the validity and reliability of the resources that the student is citing. They will let the student know if they include a reference to something that is generally not an acceptable academic resource. For example, because websites like Wikipedia can be edited by anyone online, regardless of expertise, and personal blogs may state opinions without real supporting evidence, they should not be used in an academic paper.
