HELLO;

Congratulations for your result. you are very much likely to qualify jee mains as you are on very much safer side.

Now the expected rank for your your percentile is 30502. it is very difficult to predict the actual rank and your rank might differ depending on the April exam

The rank factor for NITS depend on two factors

1. home state

2. other state

Now coming to your state Uttar pradesh there is a NIT in Allahabad  know as

MOTHILAL NEHRU NATIONAL INSTITUTE OF TECHNOLOGY (MNIT) which is comes under top 5 NITS

2019 cutoff for this institute for cse was for home state

HS    Computer Science and Engineering    807(opening rank)    1468(closing rank)

It is very difficult to get into cse branches since this branch is very high in demand therefore the cutoff for this branch is also very less

you might get into some nits  for cse branch that ill be mentioning in special rounds since the cutoff is very less  from round 1-7

These datas are based on 2109 cut offs

1. NIT manipur

special round 1

OS    Computer Science and Engineering    40345    46371

Special round 2

OS    Computer Science and Engineering    46747    47564

2. NIT Mizoram

OS    Computer Science and Engineering    43337    44693

OS    Computer Science and Engineering    47833    50215

3. NIT Nagaland

OS    Computer Science and Engineering    40345    46371

OS    Computer Science and Engineering    46747    47564

Do not worry at all since you have April attempt left and even JEE advance so you still have an opportunity to grab cse branch in top NITS or IITS.Make anote that you also have an home state quota for MNIT which comes under top 5 NITS.

BEST OF LUCK FOR APRIL AND ADVANCE!!
