I would also like an answer to Josh's question as I have the same problem: "Can I ask a question about the missing premise drills? I always seem to be getting the right variables (x or y or z, etc) in the right place in the missing premise but I never seem to be getting the signs on the variables correct (not C vs. C). Can I get some help on the principles behind arriving at the correct variable and sign for these drills?"
