How can one not agree with the content of a published paper? Is it not the case that you provide some sort of proof/argument for the content, which is reviewed by your peers?

I am the OP and while I no longer recognize the question as it's been modified so much none of my original text still exists, I appreciate the effort that has gone into editing it and am happy to leave it be :)

@Forenkazan I went to the University Of Oxford, and I can assure you, while the rank is high, the primary purpose of the MSc degrees is to make money from foreign students. They are not in the business of failing people as it would hurt their income. It doesn't mean that you will not learn anything, but keep in mind that it is not extremely difficult. I'll write some suggestions for you anyway though, if you want to prepare.

Master's degrees in the UK are not very difficult; they are designed to take money from foreign students. Very few people fail. You will do fine.
