Greetings, can you explain the double arrow concept, or at least where I can find it in the LGB? :dbl: :dblline: :some:

Hi J,

Sure, no problem!

1. The Double Arrow: :dbl:

I just explained this one for you over here: http://forum.powerscore.com/lsat/viewto ... 112#p18176. It's also in the LGB on pages 246-247


2. The Double-not Arrow: :dblline:

This is explained in the LGB on pages 244-245. Of the three arrows you reference, this one appears—by far—the most in Logic Games, so definitely make sure you are comfortable with this one.


3. The Some Arrow: :some:

This isn't like the other arrows because it typically does not deal with absolutes. It also is more or less unused in Logic Games, hence it is not covered in the LGB. It is used in LR, however, so it is covered there extensively. If you have the LRB, check out pages 382-383. These arrows simply indicate that there is overlap between the two groups (if some As are Bs, then some Bs are As).

Please let me know if that helps. Thanks!
