I remember this by: The "No" Group

All of group 4 words, even if they don't contain the word no, essentially mean no.

-NO

-NOne

-NOt Both

-CanNOt

-Never

(Never doesn't work as well for the mnemonic but it is fine)

I chose to remember these by using "A,E,I,O,U"

It isn't perfect because you have to think of "W" words instead or words that start with "U" but it was helpful.

A- Any, All

E- Every

I- If

O- The Only

U (W)- Where When

"The only" is the lone "only" indicator that falls in . group 1. Other "only" words are group 2.

Inclusive (and/or)

Feel free to grab some snacks or a drink.

Inclusive (and)

The new kitten thinks it is better behaved than either the youngest dog or the eldest dog.

Exclusive

My brother is going to stay up super late or go to bed ridiculously early.

In the inclusive (and/or) it is totally okay for the person to chose both a drink and a snack.

In the and example the new kitten thinks it is better behaved than both to the other options, namely its doggie siblings.

In the exclusive example it is simply not possible to do both.

Example:

It will not rain unless it is cloudy.

In this there are two concepts.

not rain --- group 3 indicator--- cloudy

Translation-rain then cloudy

Contrapositive- not cloudy then not rain

All we need to know is a basic subject or a symbol for it, and whether that concept starts out as a positive or negative. My example starts out with "Not" so if we choose this to negate and place in front then the subject would just be "rain" as opposed to if "cloudy" was chosen and it would be negated to not cloudy.

When you have a double negative happening it cancels out the negatives.

As an example you can think of two little siblings if Kid A is in trouble and says they didn't get in the cookie jar and Kid B tells the parent that they didn't "not not" get in the cookie jar in a snotty tone.

Kid B is saying they got into the cookie jar just using a double negative and being a pain. They could have totally thrown Kid A under the bus but they didn't, instead they chose to indirectly say what happened while burying it under extra fluff of double negations. In its own way the LSAT is doing the same by choosing the more convoluted manner of saying each contrapositive.

If the stimulus is hard then you can fall back onto the direct translation of the logical indicator to get the correct answer. Even if the information does not make immediate sense when reading it. The LSAT seems to intentionally try to throw people off by staying things in a way obscures the structure of the argument.

For those of you who noticed that "Only" is mentioned both in the group 1 indicators and in the group 2 indicators the way that I found that is simple to remember it is "THE ONLY time it is group 1 is when it says THE ONLY". Every other time that only is used as an indicator it is referring to group 2 (only, only if, only where, only when). For some reason I naturally want to start out that sentence with "the only" every time which makes it easy because it matches.

Group 2 Logical Indicators

(R.O.M.A)

-Requires (not listed but if written "x requires y" then it can be same type of relationship)

-Only, only if, only when, only where

-Must

-Always

Note: to read carefully when the text says "X is required Y" by instead of requires. In the way this is written the required part would actually be in front of the word required instead of following it.
