Guessing Strategy Theory
I've noticed a trend in the OG and even on MGMAT stuff and I'd like to get some input to see if my assumption holds any weight. What I've noticed is in some problems answer choices will be spaced out closely and then you'll see a jump in the spacing. I've noticed the option that contains the first &...

Geometry - Parallelogram Problem
http://s12.postimg.org/7iwjhqrg9/Screen_Shot_2015_11_05_at_7_07_12_PM.jpg OA : 24 Why wouldn't you add the additional triangle length to the area of 21. When I solve for x: 3x(3)=21, I get 2.3 and when I plug that in for the triangle: I get an area of 3.45 and add it to 21 for 24.45. It's close, bu...

But wouldn't that the other angle is DCB 60?? and ACD 140? I know X must be the angle on the other side too, but from here i'm c...

Meaning Concept (not actual question)
Quick question:
Does (A) always convey the correct meaning? Even if structurally incorrect.
Also, is it good practice to read and look for meaning issues before checking for parallelism, modifers, structure issues?
