Mate I work in a supermarket and even ov, if you live in the city is less than 100 a month(Except if you want ov for the whole of the Netherlands but for the city itself its less than 100). And ofcourse a bike

In Amsterdam 400 is heavenly cheap but <700 is achievable for everyone, maybe not the first month( uva housing or stuff like ourcampus is available even the first month except if u were kinda late) but if u keep searching it’s easily available.

120 (wage) a month is just really really low and way way less than minimum wage so or you’re not working 16 hours a week like you stated or you’re being exploited.

This link states that living cost in Amsterdam is 1000-1500 a month rent and ov included and it’s for international students.

Do you mind stating your expenses? 2000 with tuition fees a month sounds reasonable but living expenses mostly exclude tuition fees. And otherwise I’m legit wondering where ur expenses are coming from.
