Kitchen arrangements will vary from one uni to the next, but if it's any help to you, this is what has happened with me. There are 8 of us to a kitchen. Each one has two cupboards, one drawer, one fridge shelf and one freezer drawer. We share two kettles, two toasters and two microwaves. There is no problem with stealing, I am very lucky in that way.
Four of the flatmates pool their shopping and food and cook all together because they get on well, have similar tastes and want to eat at the same times. The other 4 cook what they want when they want, and eat alone. This suits us all fine. Once in a while, for a special occasion, we will all chip in and have a whole flat meal, where two people cook for all eight.
You will just have to get brave and try things out! It's amazing what you can do when Mummy is not there to do it for you! Start practising now and by October you should have a small repertoire of cheap and easy dishes.
