hello aspirant,

supplimentary exam means you need to give only the paper which you have failed in earlier. you have not mentioned your board. and i dont think other paper can included in suplimentary exam which you have already passed. if this year if you have cleared the supplimentary exam you can seat in jee main counselling if you have all passed certificate. if thats not possible you can give jee main next year. as jee main can be given in 3 times.
