Sorry, I completely forgot about taxes and rents. So don't be very excited about what I said early. It needs more calculations. These are very rough expenses you'll face with:
$200 - food
$400 - roof over your head
$30 - public utilities
$30 - public transport
$500 - "office" room for lectures
Total: $1160 per month.
And I know nothing about taxes of your work. Normally we get paid without knowing how much money they take away. It's about ~50% I guess.
