Since there's not an explanation posted yet, can anyone explain or point me to where Preptest 92 game 3 has already been explained? I feel so dumb, I know there's a major inference I'm missing. I didn't have problems with any other games on this exam! Gah! Any help would be so appreciated!!

Hey good evening,
I also found this tricky to setup at first but there are definitely a couple key inferences that break the game open:

6 teachers K L M N O P
into 2 schools: j/s
3 languages F G R

Rule 1: no language repeats at same school
From this rule, it is key to infer that something like FFR-GGR would not be valid, nor would FFGR-GR be valid.
Therefore the languages taught at each school must be FGR-FGR.

This is key to determine the base setup:
(junior/senior school separated by column)
F: j_ s_
G: j_ s_
R: j_ s_
(each language taught once at each school, max 2 teachers per language)

Rule 2 - KL same school, infer that K and L teach different languages
Rule 3 - LM same language, infer that L and M teach at different schools
Rule 4 - Nr - LM cannot teach r, max 2 teachers per language
Rule 5 - Of - LM cannot teach f, max 2 teachers per language
It is key to infer that L and M teach g.

P is the free piece, not affected by any rules.

LM must teach g, K follows L, would be Kf or Kr. Split boards for Kf and Kr scenarios.
Of and Nr and P fall into place based on K placement.

F: O/P
G: L M
R: K N

F: K O
G: L M
R: N/P

No other given rules on junior or senior schools, so j/s could be either left column or right column, to be determined by questions.

Hope this helps!
