How can a university student make breakfast herself every day in the dormitory where she can’t use a kitchen?

Keep an electric kettle in your room, you don’t need a kitchen for that. Just take some hot water and oats, add some fruits and maybe some yogurt (you could take a cup out of the fridge the night before). Or try preparing whatever you like for breakfast the night before. You could also keep it in a small and cheap cool box in your room.

Hi. I am in a somewhat similar situation as I am in grad school and staying with friends. Easiest is probably to keep some form of milk or nut milk in your fridge and use it with cold cereal, or hot cereal packets. There are ways to cook an egg in a microwave. Or keep some bread and nut butter for a sandwich.
