GMAT Initial Integrated Reasoning Percentiles Released
GMAT includes Integrated Reasoning section from June 5, 2012 and the initial IR perecentiles of first six-thousand candidates are released by now.
Range of scores
The initial Integrated Reasoning percentiles calculated from the first 6,229 Integrated Reasoning GMAT test takers reveal that the average score was 4 on a scale of 1 to 8, slightly lower than the mid-point score range. Some 26 percent of the test takers scored a 1 or a 2, and 30 percent scored 6 or above.
Integrated Reasoning and Total GMAT score
Introduced as a separate section with a separate score, Integrated Reasoning does not affect the Verbal and Quantitative sections and does not contribute to the Total GMAT score. Schools can compare Quantitative, Verbal, and Total scores directly, using the IR score as an extra data point in their admissions decisions.
