Some questions about MFA Interaction Design Program

Hello everyone,

I am a college student from Taiwan and now majors in German. Recently I developed interest in Interaction Design and look forward to apply SVU's MFA Interaction Design after I graduate from college. However, as a student with zero design background, I am not sure where to start. Would you suggest what kind of technical skills and knowledge  I should prepare myself before I apply? (For example, what computer programs should I learn or others, etc.) Also, is it possible to request to see the portfolio examples from the past applicants? Because the  portfolio requirements written on the website is kind of abstract to me.

It It would be a great help if someone is willing to reply.

Thanks!
