Student metrocards have more restrictions on them. You can only use them 3 times either on your way to school or on your way home. That s it. However, you should still be able to use your student card the same way you would any metrocard. Just use it when you transfer. If you have not transfered too many times, the card should permit the transfer.
You simply made a metrocard transfer - BS!
How do you think you make one? You live here, you should know how to use one of those.
