The Week is a good one.
Speed Distance Time stuff.
Also, if making it onto part two, they assess you (as NCA) mostly on how you perform as a team MEMBER, not a leader. Guy from OASC did a talk at our UAS, and that is what he said. So when not leading, make sure you are concentrating on helping out, and not trying to take over the leader's lead. Seen it happen.
Good Luck!!
