Hello Aspirant,

See rank in any examination cannot be zero even if you have scored zero marks or even negative marks because ranking system starts from 1 and first rank is allotted to the candidate who has scored highest marks in the examination now for the candidate having lowest marks wil be having the maximum rank. For e.g. if total 5 Lakh candidates appeared in the examination and you scored the minimum marks then you will be having your rank around maximum i.e. around 5 Lakhs.

I hope this information helps you.

Good Luck!!
