### Last minute LG question: Best way to do rule-sub questions?

The rule substitution question that appeared on PT 57, 58, and 59 appears to be a new type of question. I was caught off-guard when I first saw it, and I guessed correctly. The 2nd time, I figured it out but not through any solid method. The 3rd time, I kind of had a method worked out, and I was just wondering if it's the one you all use.

So when I get a rule sub question, I refer back to all my prior hypotheticals, and I apply each rule sub to see if I would get the same result. If an A/C proposes a rule sub that doesn't correlate with a prior hypothetical, then it is crossed off. You'll usually need at least two hypotheticals because unless you're lucky, one hypothetical will usually not eliminate 4 rule subs. I just keep doing this until there's only one A/C left with a rule sub that's consistent in every hypothetical.

Is this the method?

I haven't done those PTs yet, so I'm not sure exactly what you mean, but it sounds to me to be nothing more than a "Which of the following, if true" question, or similar to a "suppose if a rule says...". I could be wrong, however.

This is exactly what i am doing. for the game with a substitution question, I mark all the possibilities that worked before in other questions in that game so I can use them to see if the sub rules are working or not. I am pretty sure this is a solid method. I hardly miss a question on LG.

well any deduction you made with the old rule is invalid, but the other rules still stand.

normally, you just need to make a subtle change.

there's no "approach." just treat the new rule like you would any other rule, and make any deductions you can to save time.

by the way it's not a new thing, it's been on about half the sections since PT 1.

I think it's pretty new. I've done PTs starting from 9 and I've never seen questions quite like the one I'm talking about.

Maybe you're talking about the ones where they introduce NEW rules? I remember those. But the ones I'm talking about are different because they introduce a new rule yet they still want the same effect as before.

Why am I still on TLS? Good night all!
