How much are you expected to know?

I am an ED Newgrad in a NSW hospital. It is my 6th day today and I feel dumber than I’ve ever been 😭 I simply can’t seem to get it. The whole HIRAID, ACAT, undifferentiated patients, it is all new compared to what we learnt at Uni (plus I didn’t do an ED placement). How soon are you expected to grasp it all? How soon are you expected to look at a patient and instantly know what focused assessments you’re meant to perform? I am still getting used to having to dispense medication without another adult checking them with me🥲 I feel useless 😕
