Forgot the exact procedure, but:

- If you miss too many (>19%) then the computer gives you some extra questions in the hope you'll answer enough correctly to get above 80%.
- You will be debriefed and subjected to a pseudo oral to discover what went wrong. If you know the answer (as in the crew life vest color example I gave) then you're probably good to go.
- If your response in the debrief is an honest admission of a legitimate problem which might have distracted you (at our age we had quite a few babies being born, folks moving, etc ...) then Delta will probably do everything they can to get you some time to handle your business, refocus and pass the training.
- If your situation involves a lack of discipline ... you've got a problem and I dunno where it goes from there.

It is not a wash out program at all. The MD88 and the 737 are not as pilot friendly as newer designs, but if you survived the E-120 or that generation of turboprop equipment you'll find the MD88 easy, if not familiar.

The CRJ's are such easy aircraft overall that they would transition nicely into the 757 / 767. That option will probably not be around for a while. (the 767 flies a lot like an overpowered -200 with a better wing). The MD88 flies a lot like a turboprop with twice the power and half the wind sawed off by an inebriated monkey with a sawzall. The systems were designed by the monkey's uncle who sold heroin out of a junkyard full of DC-10 parts. Control responses are pure ATR72 (if that's any frame of reference). The junky monkey now works for Boeing performing QC on 787 parts.
