How do you place your acceptance deposit?

<p>Hello,I am an international who was admitted to Amherst class of 2018 and I am seriously considering going there. I received the acceptance packet yesterday. I was wondering how I attach the required $400?Is it by cash or a check or can I do it online. Also,I am unable to access Currently Admitted Student’s page,Is this a bug or should I be worried?I heard some students received a mistaken admission letter.Could this have happened to me?</p>
