Hm 2019 me jharkand bord se 12th pass hue h nd 2020 me mains dege to top 20 prcentil mera 2019 ke top 20 percentile s cmpare hoga ya 2020 se
Dear aspirant, if you are sitting for exam in 2020, the percentile will be compared with the top 20 percentile students of 2020 only, as you are a 2019 passed out so you will be considered a dropper . So prepare well as competition is getting tough every year.
Hope it helps.
All the best:)
