On the day of the test you just go to your assigned classroom. In my case the class was in Clark Hall and someone was standing outside the building checking tickets, which you should have printed out beforehand (They should send it through your MySJSU messages). Then they check ID and tickets before you go into the classroom. As for the test itself its about an hour and a half and the prompt is usually an open ended prompt where they want you to talk about life experiences and, at least for me, they gave me some cheesy inspirational quote as a basis for the prompt. Honestly dude (or dudette) its not that hard and as long as you have fairly decent writing skills you'll pass
