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".
Do not chase "tricks/tips/shortcuts". Chase "concepts"!Do not chase "scores", chase "learning". Scores will follow.

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".
Compound Interest= P[(1+r/100)^n –1]
P: Principle invested.r: Rate of Compound interest.n: Period.
Semicolons are used for joining two independent clausesAmy sings; she enjoys it. - Correct!

Irrational: Can’t be presented in p/q form, where p and q are integers. Ex: √3, Pi
Rational: Can be presented in p/q form, where p and q are integers. Ex: 2, 0.45, 3/7, etc.
