Couple of careless errors here, overall, I think my grasp of this is pretty good.

Data Sufficiency

Things one must know:

• Rephrase both the question and the statements if you can by reducing it into its simplest form and focusing how the piece of information relates to the question.
  
• Factoring algebraic expressions is a great way to un-disguise hidden information
• Value questions - find a single number to answer the question.
• Yes/No questions - conclusively answer yes or no
• When testing numbers try to prove the statements not sufficient, be sure to try fractions, negatives and zero unless you are specifically told in the question that the variables have constraints.
• The statements cannot contradict each other - allows you to detect any mistakes you might have made.
  

PEMDAS

Things one must know:

• PEMDAS
• When an expression with multiple terms is subtracted, the subtraction must occur across every term within the expression, each term in the subtracted part must have its sign reversed.
• Pretend that there are parentheses around the numerator and denominator of a fraction. This is easy to forget if you eliminate the fraction bar or add or subtract fractions.
