I haven't done a philosophy essay in a while and I'm level 3 now (i had some time off). How many references are we meant to use? I was told that in level 3 you're meant to cover things in more depth and I only have 2,000 words. I've planned to write about 5 theorists but this would only mean 5 sources which isn't a lot. What's the minimum needed? I don't want to get marked down for not having enough but also don't want to likewise get marked down for covering too many too broadly!
