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.
Backup strategy: On the real GMAT, if you get an RC that you just can't comprehend......you must mark randomly and move on...
- Don't let one RC decide the fate of your complete GMAT score.-- Rather, save time and get the remaining questions correct!
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".
The error of comma splice occurs when two independent clauses are joined using a comma.Example: Amy sings, she enjoys it.Correct: Amy sings; she enjoys it.

MANAS: Many, Any, None, All, and Some can be singular as well as plural.

Percentage change:
[(New Value-Old Value)/ Old Value] x 100
Please note: the denominator has "old value".
"Like" is used for "comparing nouns"."As" is used for "comparing actions"."Such as" is used for "giving examples".
On the verbal section, be cautious when you see an answer choice with "extreme" emotion.
Answer choices with "moderate" tonality have a higher probability of being correct.
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.

Rhombus is a quadrilateral with all sides equal.Area: 1/2 x diagonal 1 x diagonal 2
If angles of a rhombus become equal, a rhombus becomes a square.- And the diagonals become equal.

In DS, an answer is achieved only when the answer is "consistent".
Q. Is X a multiple of 24?(1) X is a multiple of 6.(2) X is a multiple of 4.
X = 24 satisfies both (1) and (2), leads to "Yes".X = 12 satisfies both (1) and (2), leads to "No"."Inconsistent". Hence, insufficient. Answer is E.
