GPS preference

(Is this GPS 1.2 (week 3, challenge 9) that hasn't happened yet - and can we assume (not being allowed to look at it) that it has Ruby content if it's being scheduled this way?)
(Or is this the mandatory peer-pairing - challenge 3 from week 4?)
(Or are we doing GPS 2.1 from week 5 or GPS 2.2 from week 6 ahead of time?)
