Regarding XAT 2018 Marking Scheme

Marks scored in General Knowledge section are not added to the final XAT result and merit list. But it may be used for final selection in XLRI Jamshedpur and other top b-schools accepting XAT score for their further evaluation procedure.

Even the colleges which uses this score doesn't generally use this score during the calling procedure but they may ask questions related to it during your second round of interview and may also use the score in the final process. But as said earlier it does not define percentile and completely depends on b-school to whether use it or not.

All the best!!
