In DS, "combine" the two statements only when each statement fails alone.
Q. If X is an integer, is X a multiple of 12?(1) Two of the factors of X are 5 and 7.(2) X is a product of two odd integers.
The answer is not C. The answer is B.
"model...after" is a correct, idiomatic usage
Sara modeled the statue after her mother. : Correct
Do not chase "tricks/tips/shortcuts". Chase "concepts"!Do not chase "scores", chase "learning". Scores will follow.
If it really comes down to "guessing" on the GMAT...
- On SCs, go for the "shortest" choices.- On RCs and CRs, go for the "longest" choices.- On DS, go for "C".
Schedule your GMAT (only) once you get your target score on 3 consecutive mocks!
On Verbal questions, don't "Select 1 choice."Rather, "Eliminate 4 choices."
In DS, beware of "exceptions".
Q. Is X positive?(1) |X| = X.
Because of the exception "X = 0" case, this statement is insufficient.
"Do so" is the correct usage when "so" refers to an action."Do it" is the correct usage when "it" refers to a noun.
As "do" generally refers to actions, "do so" is more often correct than "do it".
60% of the learning comes from analyzing mistakes!
The mind-map-strategy for RCs
1.Skim through the first paragraph.Take your eyes off the screen.
2. Ask yourself the paragraph's "purpose" .Purpose is always very, very brief.Avoid paraphrasing the details.
3. Skim through the next paragraph.Take your eyes off.Ask yourself the paragraph's "purpose".Link the purpose of the first paragraph with that of the second.
4. Keep repeating Step 3 for all the subsequent paragraphs.
Don't exhaust official material early- it's a common mistake.Save it for the last few weeks.
Even x Even = EvenEven x Odd = EvenOdd x Odd = Odd
Even + Even = EvenEven + Odd = OddOdd + Odd = EvenOdd + Odd = Even
In DS, when you are able to solve "too easily", you are probably missing a trap.
Q. Which integer is the highest common factor of four positive integers A, B, C, and D?(1) A= 27, B=49.
Unlike what many students will think, this statement is "Sufficient". Because no matter what "C" and "D" are, if HCF of "A" and "B" is 1, the answer is going to be "1".
