  • Here is the answer to my question - is the PR review of major Math and Verbal topics enough? PR said in the 43rd page this book cant take the place of a basic foundation in math. If someone needs that, then they are suggesting to buy PR's book "Math workout for the GMAT"; but one gud sugn again from PR - "If your purpose it to raise your GMAT score, it’s a waste of time to learn math that wont be tested" - gud one isnt it??
  • Imp. In MATH: when you finish a problem, always take 2sec to reread the problem to make sure you've actually answered the question
  • Some math that I've learnt new/refreshed from PR
    • Divisibility rules:
      • A no. is divisible by 3 if the sum of its digits can be divided by 3 (without remainder of course!)
      • A no. is divisible by 4 if the sum of its last two digits can be divided by 4
      • A no. is divisible by 6 if the divisibility of that number by both 2 as well as by 3 works :)
        • IMP NOTE: ETS never puts 0 in the remainder
    • Comparing fractions:
      • To compare, multiply numerators of one fraction with denoinators of the other; where this product is more, the fraction of that side is greater!
    • Probabilities, Permutations & Combinations always challenge me!
      • Coz I did not learn these in my acads (I'm not sure if I'd skipped this chapter then!)
    • Some Techniques
      • Try plugging the answers in the question to find the right answer, but only if the question si relatively straight forward and if the answer choices are numbers - always start with the middle answer, if the result is too small, try then the next larger answer; if the result is too high, try the next smaller one
      • In problems where 'must be', 'could be' or 'cant be' PLUGGING IN always almost helps, but you may need to plug in more than one number
