Hey Natasha,
A common problem that students face when going abroad is how to pay the least amount of brokerage fees to organisations that specialise in converting currency. The best way to reduce the amount spent in converting currency is to convert them at your banks instead of going to Airport Kiosk and converting money there. This is because Airport kiosks have greater commission rates than banks usually do. Banks also tend to have schemes that you could take advantage of to reduce the price of conversion even more.
