i guess that's their standard offer for such a position. yes it's not enough, i think receptionists from some schools get double. anyway let me give you a breakdown. if i were to receive the same package here's what i'd do :

 1000  send back home

 600    groceries (150 a week)

 500    transpo  

 500    allowance (internet, call cards, etc)

 420    savings

again, it's just me, i don't go out that much and it also depends on how much you need to send back home. goodluck!
