I need help with this question (ENGLISH LIT STUDENTS)

before I start: I do not want someone to write the essay for me, I just need help understanding what to do with this essay and what it is asking of me, as my teacher isn't responding to his emails and I really need help so I can get a 2:1 or above.

I tend to go off track or not answer the question and since he may be of little help in this scenario I may need yours!

The question is asking me to do comparison of two textual versions of Othello.

1) I can limit the analysis to a single scene if need be.

2)The required terms are that I have to draw explicitly on the Shakespeare module materials examining the Quarto (Q) and Folio (F) versions of Othello.

3) I have to limit my analysis to just TWO versions of the same play.

Any help related to structure, and how I should write it, even simple terms of what the question is asking me would be of help. I have found university fine up until this module, this class has bee very challenging and I am failing to wrap my head around it. I just really wish he would respond to his emails and wasn't such a harsh marker...
