Hello,

As you said that the first time you gave jee you failed in 12th and next year you are passed in 12th. So now, again you have to give jee to get admission into IITs, NITs, IIITs and many government colleges and the colleges which are accepting candidates on jee mains marks. The JEE score is valid only for that year. So again you have to qualify it.

Hope it helps.
