This may be an easier way, especially if you have 2 people working toward their card.
Both players play LW (no faceoffs, even on PK), and both keep pulling their goalie (LB+Back). Make sure both players get 1 goal, 1 assist, although we occasionally settled for 2 goals, or just 1 point.
Other than that, stay in position the best you can, get hits when you're sure you won't get a penalty, and try your best not to turnover the puck.
Quit every game after 5 minutes, or once each player has their points. Doing this method kept me going back and forth between B+/A- overall, and went by very quick.
