For Quant Problems, especially for overlapping set questions, remember to not just solve for x, BUT ANSWER THE QUESTION ASKED!!!!

Triangle Inequality Law:  Usually only given 2 sides.  Of the 2 sides:  The third side lies between the difference of the two sides and the addition of the two sides = (7-2) < k < (7+2)

For Geometry:  Cylinder problems - Sometimes you are given only half of the volume in the cylinder, but asked for the diameter of the entire cylinder.  Don't solve the problem using half the volume, but instead extrapolate the volume to be for the full cylinder.

Standard Deviation: (Dff-  Avg)^2 for all values  (=VARIANCE)  -->  Divided by total number of values  --> Square the result

Data Sufficiency: Sufficient or Insufficient to answer the question.

Quant: Rephrase as much as possible in Data Sufficiency questions.  Find similarities in the question and the two answer choices
