Ask the girls out.
You: Come. Let's go to the [library/canteen/park/Mathematical Science building/ Physical Science building].
If they go with you or a girl goes alone with you that's compliance #1. You also get massive social proof if a bunch of girls are hanging out with you. You then try to get compliance #2.
You fish for several compliance from girls until you are isolating a girl in your apartment or dormitory.
Shift your slow sarging style of "Is that an IOI?" into a more active, fast paced, "Let's go."
