I put the option (pearls 7&8 for one of them), no idea if its right though, didn't check it
i put that too, wasnt really a guess either i worked my way through it
s1 = reasonable
s2 = screwed up to the extent where i starting counting how many option "A"s i put (ended up being 18) im glad everyone found it difficult though,
s3 = pretty good, much easier than medentry. but i ended up guesstimating like 5
only ambiguities for s1 were the 'false positive and false negatives' - i swear that didnt make sense

did anyone else put 60% for the answer?
Also, did anyone manage to figure out the cube question?
where some kid builds two cubes, and his teacher 2,3,1,4 or something?
I was tossing up between 3,2,1,3 and 3,2,3,1 or w/e it was..couldnt find a relationship for the last two digits
