Hi !

The validity of JEE scores is typically limited to the academic year in which the exam is taken. JEE scores are generally valid for one year only . If you took the JEE four years ago, it is likely that the scores from that year are no longer valid for admission to undergraduate engineering programs.

The cutoff mark varies for every college depending on the JEE Main Marks . The JEE Main Marks are useful to get admission in NITs , IIITs , GFTIs .
