It really depends. For eg u're an arts student in Paris,
education's free, living expenses high, and u're probably gonna
have alot of difficulty finding a job unless u're already fluent in
French or a native speaker, plus the work must be related to what
u're studying.. so basically u gotta have most or all of the money
upfront..
But if you're an arts student in Melbourne, Australia, school fees
and living expenses are moderately high, but you can easily find a
job if u're outgoing (20 hrs of work above the board anyway, most
places let you work more, I easily earned over A$1.6k/mth doing
part-time waitressing because the tips are high). So you can start
off with just enough for the tuition fees, land a job and use that
to cover living expenses )
