if u have a ov studentkaart u may have on some days of the week.
but to get a ov studentkaart u must have the dutch nationality or a type 1 id (more info at old topics)
if u dont have a ov studentkaart u can buy a ns kortingkaart.
its a discount card for the train. 40% discount after 9 am and in the weekend.
its cost 35 euro for one year.
不是35欧是55欧 错了 对不起
