Hello, I am Shaddi

2-    What transport is best for me like taxi or Metro Train etc...?
3-    What is the minimum expense for a student to survive a whole month with food, transport and accommodation in Helsinki?
4-    What minimum salary rate of an hour or complete month for a student?

Thank you
