Student cost of living in Poland (Transport / Rent / Food / Courses)?

Heya! Now ive seen hundreds of threads bout the cost of living in various cities, but have not yet read about costs and expenses in the students life. Anyone has insight?

The way I see it, monthly:
Transport - $100
Czynsz & oplaty - $350 shared (or more if indie room)
Food - ???
Courses & study material - ???

As some might know, ive posted about various avenues to pursue for new travellers to poland, and came with 4 solutions: teach, work, business, or save up some savings to recon the country. I havent investigated yet the possibility of being a student. REALLY interested to know costs.

This must be if you own a car?

I guess the expenses depend on the budget you have and the city you live in, it's hard to say how much an average student spend monthly, everyone is used to different standard of living, so it's hard to say what you're expecting to hear.

A monthly bus/tram pass will set you back more like $30.

Alright, well based on (polishforums.com/work-study-43/much-average-living-cost-poland-foreign-student-53612/) that post I'll just have to assume around 1200zl shared and maybe 1500zl single.
