GMAT Prep - Flash Blog (akin to flash card)

From my last post, my GMAT prep tempo has reduced a bit. We had a major software release at work. And the bugs introduced by that release has had me busy. At the same time, my responsibilities have increased and I am handling more Clients directly. It would definitely reflect great on my performance review.

I am listing the tests I have completed and what I have pending:

Completed

1. Princeton Review - Verbal Tests - Bin 1, Bin 2, Bin3
2. Kaplan Coursebook - All Verbal section questions
3. GMAT reference - All math reference material
4. Kaplan - Math - did session 4

To Do

1. PR - 4 CAT tests
2. PowerPrep - 2 CAT tests
3. Kaplan Higher Score CD - 8 Verbal tests & 9 Math tests
4. Kaplan Coursebook - All Math section questions

I am going to have to list the common mistakes I am making so that I try and improve on them

English:

1. RC - Need to formulate the central idea while reading
2. SC - Need to pay attention to idioms when in doubt
3. "A number" of vs "the number of"
4. Fewer is for countable. Less is for uncountable
5. Not only...but also
6. Pronoun - Remember to subsitute the single entity when in doubt...You and I need to go there (Drop the you and the sentence should make sense)
7. whom and who. If the sentence can be recast as a question and the appropriate usage is him, then whom should be used. If the appropriate word is "he" then who should be used
8. Each, Anyone, Everyone, Everybody, cache, crowd is singular.
9. Remember that the modifier may be wrongly placed.
10. Parallel structures - sometimes may not be underlined. So pay attention to the sentence in its entirety
11. If the sentence does not sound grammatically incorrect, remember that choice A may be the best.

12. Read all choices and use POE

13. Avoid extremes in answer choices - GMAT is not extreme.

Math

1. Quarter is 3 months not 4 months
2. Units should be right
3. Look at all choices.
4. Pay attention to "at least"
5. Use substitution of numbers. "Plugging in"
6. Substitute the final result in algebra to ensure correctness
7. Percentages should be carefully done
8. Work formula T = (AB)/(A+B). Remember to multiply this by the number of units being worked. For e.g If person P1 takes A units of time to paint one room and person P2 takes B units of time to paint the same room, how much time would both of them take to paint 2 rooms? First find the answer for one room and then multiply by the number of rooms: 2
9. Probability: Sum of all probability = 1.0
10. P(A not happening) = 1 - P(A happening)
10. P(AB) = P(A) * P(B) [independent events]
10. P(A or B) = P(A) + P(B) [ mutually exclusive]
10. P(A or B) = P(A) + P(B) - P( A and B) [ not mutually exclusive]
11. Combinations (Order does not matter) - n!/(k!)(n-k)!
12. Permutations (Order does matter) - n!/ (n-k)!
13. Probability
