Will there be any Benfit This year ....As In every attempt only 6 lac average student are Appearing...Or there is only LOSS as Scoring Percentile is getting tougher because of low student per attempt.......Koi faayda hoga ?

I assume you are talking about JEE MAINS.

See if every attempt there are less students, and if in each attempt the ratio of good students is larger then obviously the percentile shift will occur. So this can't be said accordingly that due to the lower number of attempts you will get a lot of benefits but yeah! to some extent the competition may get lower in the average zone i.e., >80 percentile. But in the range 90 percentile to 100 percentile, the competition will be on , so you should prepare for it and don't think of such arbitrary trend shifts.
