Hi Pulkit, there is no fixed percentile for any score in CMAT. It varies every year based on the difficulty level of the paper, number of seats for admission, number of test takers and so on. But going by the past records, 238 can be 95+ percentile mostly. However you can refer to our percentile predictor and pathfinder for detailed description,
