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".
In DS, "no" can very well be an answer.
Question: Is X = 7?(1): X is not a prime number.(1) is sufficient. Because (1) leads to "No, X is not equal to 7".
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.
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.

Spot the error: Teacher taught that the Earth revolved around the sun.
"revolved" is not correct. It must be "revolves".(Universal truths are always conveyed in simple present tense).
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.

Don't leave mocks for the end- it's a common mistake.Take a mock every week.
A fraction will terminate if its denominator has no prime factor other than 2 or 5.
17/160Prime factors of "160" are "2" and "5". So, this fraction WILL terminate.
13/480One of the prime factors of "480" is "3".So, this will NOT terminate.
