"Circular Reasoning"- The fallacy of assuming a conclusion to be true, in reaching the conclusion.
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.
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".
60% of the learning comes from analyzing mistakes!
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.
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".
Don't exhaust official material early- it's a common mistake.Save it for the last few weeks.
On Verbal questions, don't "Select 1 choice."Rather, "Eliminate 4 choices."
A sentence in English can end in just 3 ways: period, question-mark, or exclamation mark!
Approach for CR boldface questions:
Step 1: Identify the conclusion.Step 2: Link the bold part(s) with the conclusion.Step 3: Know what to expect from the correct answer choice.Step 4: Eliminate four choices.
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.
Pi doesn't define circumference. It's the other way around.
Ratio of circumference and diameter is always constant. This constant is "Pi".
