Hi

There's no  75 % criteria in 12th to be eligible for jee main, so even if your% is less than 75 % you will be eligible for jee main 2023.

For your reference,

Jee main eligibility criteria is given below-

---------------------------) Qualification required :- to be eligible  for JEE mains you need 10+2/equivalent qualification from a recognised board.

-------------------------) Passing year :- one is eligible for JEE main examination for consecutive three years starting from the year of appearing for 12th /equivalent examination i. e to be eligible  for JEE mains 2022 you should be either appearing for 12th board exam or equivalent  in 2022 or should have passed it in 2021 or 2020

-------------------------) There is no age limit to be eligible

- ------------------------) there is no minimum percentage requirement to be eligible for JEE Main for BE /Btech.

But yes,

To be eligible for BE/BTech  in NITs, IIITs, CFTIs one needs at least 75% marks in class 12th if belongs to General or OBC category  or at least 65% marks in class 12th if belongs to Sc or St category or needs to be in top 20 percentile of their board examination.

IMPORTANT NOTE :-  This minimum percentage barrier of 75 % - 65% for NITs, IIITs, CFTIs  has been lifted off for jee main 2022 . It means to be eligible all you need to be eligible is to have at least passed 12th .

To be eligible for NITs etc in 2023 what you can do is give 12th improvement examination in order to get 75 % or more so that even if 75 % criteria returns in 2023 you will be eligible for NITs etc .

But as you are interested in DTU, nothing to worry because for DTU required% is only 60 % in pcm aggregate.

Here's the DTU eligibility criteria:-

To be eligible one must pass his or her class 12th board examination with physics chemistry mathematics and English and must have got at least 60% in aggregate of physics chemistry and mathematics
