1 is not a prime number.A prime number must have exactly two factors. "1" has only one factor.
On the real GMAT, every question is important.First few questions on a section are a bit more important.
In DS, beware of "exceptions".
Q. Is X positive?(1) |X| = X.
Because of the exception "X = 0" case, this statement is insufficient.
Commas cannot join two independent clauses.Incorrect: Amy sings, she enjoys it.Correct: Amy sings; she enjoys it.Correct: Amy sings, and she enjoys it.
"Confusing-correlation-with-causation"
A favorite GMAT CR fallacy.
Example: Grandma sneezed, so a tornado hit Nebraska.
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".
"had" is used to denote earlier of the two actions completed in the past.
Example: Although the play had ended, some audience stayed in the theatre.
Schedule your GMAT (only) once you get your target score on 3 consecutive mocks!
