#feedback Since the "oldest mistake in the book" is mistaking a sufficient condition for a necessary conditions (right?) there should be a 3rd step to these practices of "what is the mistake?"

For example: Where the judges are independent there will be a good legal system.

JI --> GLS

/GLS --> /JI

What is the mistake? GLS --> JI

Defining the trap would help avoid it.

How important is it that my results are identical to the answers? For example, on #1, I used the wording of the example:

without P.E. --> H.D.

and then

/HD --> / without P.E.

The answer uses the "/" slash in place of the "without." So,

/(physical exercise) → health deteriorates.

Are both right? Is it best to keep original wording?

Hi! I am currently at a 167 BR (163 without BR & trying to break into the 170s), I'd be down to review and study together -- right now I am just missing the "harder" and "hardest" questions and feel like I have a strong understanding of everything below that, so it could be awesome to improve my understanding by explaining questions and work together on those especially hard ones.
