<p>For clarification, Stanford does not consider you for SCEA if you are not matched–thus you have only two opportunities to apply: once through the Match process, once in the RD (if not matched). In either case, you have to complete the Common App. But applying to SCEA carries a significant chance of being rejected, whereas with the Match process, you are guaranteed at least another shot in the RD round (deferral). Most Quest Scholars at Stanford are actually admitted in the RD round–100+ in most years, I think. Still the acceptance rate is <10% but you do get special consideration, being in an identified pool, in both rounds.</p>
