What is percentile base calculation in RRB Group D exam?

<p>Percentile scores are scores based on the relative performance of all those who appear for the examination. The marks obtained are transformed into a scale ranging from 100 to 0 for each shift of examinees. The percentile score is not the same as the percentage of marks obtained. The percentile score indicates the percentage of candidates that have scored equal to or below (same or lower raw scores) that particular percentile in that examination. Therefore, the topper (the highest score) of each shift will get the same percentile of 100 which is desirable. The marks obtained in between the highest and the lowest scores are also converted to appropriate percentiles. According to the revised marking scheme, the boards have decided to interpolate the raw marks into the base shift.&nbsp;</p>
