GS S&T Superday, advice?/did I make it?

So I had my first round interview for GS S&T - Securities Division and my status on gs.com just changed to "additional interviews required" and says they will contact me soon about travel, expenses etc. Despite this status change I have yet to receive an official email. I am assuming this means I made it to a superday? If so, advice? I have participated in superdays before but this will be my first for S&T. Should I expect instrument-specific questions, math, probability/brainteasers, behavioral, or basically everything?
