Took cracku data in excel and did some analysis:
Slot 1 ;
Total candidates: 620
Average marks : VARC = 49.08387, DILR = 45.36935 QA = 51.72097 OA =146.1742
MEDIAN;
VARC = 48, DILR= 45 QA= 50 OA= 141
MODE;
VARC=52,DILR= 45,QA= 50, OA= 126
Number of people scoring their highest marks in VARC(among their own score)=226
Number of people scoring their highest marks in DILR(among their own score)=138
Number of people scoring their highest marks in QA(among their own score)=277
Slot 2 ;
Total candidates: 816
Average marks : VARC = 51.66422 DILR = 38.80637 QA = 54.2549 OA = 144.7255
MEDIAN;
VARC= 52, DILR= 38 QA= 54 OA= 140
MODE;
VARC=52, DILR= 33,QA= 58,OA= 120
Number of people scoring their highest marks in VARC(among their own score)=362
Number of people scoring their highest marks in DILR(among their own score)=36
Number of people scoring their highest marks in QA(among their own score)=439
OVERALL AVERAGE;
Total candidates; 1436 VARC = 50.55014 DILR= 41.63997 QA= 53.16086 OA = 145.351
MEDIAN
VARC = 51 DILR = 41 QA = 53 OA= 141
MODE
VARC = 52 DILR= 45 QA= 50 OA 122
Number of people scoring their highest marks in VARC(among their own score)=588
Number of people scoring their highest marks in DILR(among their own score)=174
Number of people scoring their highest marks in QA(among their own score)=716
It is clear from this analysis varc and qa were tough in 1st slot and dilr in 2nd
also point to be noted it seems varc markin will drop below qa this time so 30 marks can fetch you 90 percentile(it seems from this data) .
