Do I have to use the 6 major world religions in my R.E exam?

Do I have to use one of the six major world religions or can I use any? This morning I had a mock R.E exam and in most of my answers I used Christianity and Buddhism. However, for some answers I referred to the cult of Cthulhu, the Church of Jediism and the Church of Euthanasia. For example:

"All religions are sexist" Do you agree (3 marks)?

My answer: I strongly disagree as their are many religions that are not sexist. For example, the church of Euthanasia believe that everyone should kill themselves regardless of gender. Furthermore, the cult of Cthulhu believes that both male and female are equal slaves of the dark lord, the great old one Cthulhu. Lastly, the church of Judaism allows anyone to become a jedi once they take an oath.

Will I get the marks?
