So I will be living at a house with a few other students for the year. Commuting isn't an option =( and housing isn't given to seniors

Anyhow I have begun budgeting everything. I've made a list of known expenses (rent, permit, etc.)

However I am having a hard time decided how much to budget for…groceries. I have lived on campus with a meal plan. I would appreciate some input!

Any other tips will be greatly appreciated! Thanks =)
