LSDAS policy is to disclose ALL courses taken for attempted college credit, even if not going for a degree. (so disclose)
As for the expunged record, each school may vary. But if they ask (as they often do) for ALL arrests, even those not leading to conviction, or those expunged, then obey the instructions given. -If by some fluke they only ask for actual convictions on record, then only give what they ask.
