RFM question now that bid day is here

[NWGreek]

My daughter is going thru recruitment and is seeing her favorites disappear each round and is feeling very disheartened. She still has a full schedule and I am encouraging her to be happy about the really strong chapters she still has on her list. However; there are a few she is really not loving that stay on her list each round. I am of course, anticipating the worst case scenario, so, for example, if she had 2 she really liked at Pref and one she really would not accept a bid from, what is the out come if she lists 2? If she got neither could she be eligible for a quota ad or a snap bid? I have never been clear about the difference. Thank you - I wish it were acceptable to have a glass of wine at work.....
