Budgeting my OSAP

I've only budgeted small amounts (like my work income) before. I have a whole sheet for that. But I'm wondering how y'all budgeting your OSAP. Im using it to pay for my living as my tuition is covered. I have a total of 13k which could potentially cover the entire year (12 months). Potentially as in I would probably also need to pay some bills in my own. Do you guys just sorta divide it up and pay the rest on your own? My current monthly expenses go for around like 1.3k. Should I just divide it all up? And pay for things in cash?
