Be cautious when you see extreme tonality on a CR question or answer choices.Example: must, most, highest, lowest, worst, best etc
- Often, the key to elimination/selection of an answer choice lies in such extreme terms.
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".

What is the remainder when (100! + 17) is divided by 7?
100! is a multiple of 7. So, it leaves remainder 0.17 leaves remainder 3 with 7.
So, the answer is 0 + 3 = 3.
Comma followed by present participle (verb+ing) generally leads to a cause-effect relationship.
Example:Jack performed brilliantly, leaving the audience delighted.
Difference between "Inference" and "Conclusion" on CR:
- Inference is any statement that can be derived from the passage, without any assumptions or extrapolations- Conclusion is the main point of the passage.
- "Conclusion" is a subset of "Inferences".-- The "main inference".
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.
Don't leave mocks for the end- it's a common mistake.Take a mock every week.

A favorite GMAT CR fallacy.
Example: Jack cannot lie because Jack always tells the truth.Example: A is true because B is true; B is true because A is true.
