Writing my first proper essay for MSc and I love it but am also a bit terrified 
How do I know if it's good enough quality to pass? Everyone bangs on about the jump from undergrad to postgrad, but it's ages since I did my degree.
Ideally, I want to get a decent grade and not just pass - I think the key to this is good critical analysis, but I feel like I don't have enough words to do that with a complex topic. My word count is 2500.
Any tips or ideas for writing good essays at postgrad level?
