Engineering

As I myself got 185 marks in JEE Main and cracked JEE Advanced with a rank of 20k and went through JoSAA in 2017, I think I am the right person to answer this. First of all, I would like to say you that you cannot predict about the marks very accurately so rank should be the parameter. Coming to NITs, there are 3 tiers of them. Not all NITs are the same. If you want to get CSE in any of the tier 1 NIT, then your rank should be less than 2000 in JEE Main. If you want CSE in any of the tier 2 NITs, then your rank should not exceed 5000 in JEE Main. And if you just want an NIT tag (which you shouldn't as NIT tag is not any big tag), then for CSE your rank should be less than 10,000.

Well, the best colleges through JEE Mains are:
NIT Trichy: average CSE package (17 to 20) LPA.
IIIT Hyderabad: average CSE package 26 LPA
NIT Rourkela: average CSE package (15 to 18) LPA
NIT Suratkal: average CSE package 17 LPA
NIT Warangal: average CSE package 18.55 LPA

BIT Mesra: average CSE package 14 LPA

IITH, IIITD, IIITB are private institution & rests are Government institutions.

Biotechnology in VIT is great. You'll hear pretty harsh critics about this institute but that is because of its stringent and over-the-top rules, else this is actually the best institute in India for Biotechnology. I'll state some simple but essential points that makes this institute the best for Biotechnology in India
1. 99% of the faculty for this branch are Ph.D. holders from prestigious institutes around the world. Their knowledge about the subjects showcase their experience and can build up your interest in even the most low key subjects.
2. The content of the syllabus is inspired and adapted from top notch Universities around the world so it's a curriculum that you would get in a Stanford or Cambridge or other big University with a little Indian touch to it
3. Most professors here focus on how well you understood the content and not how well you learned it. So it really helps you have good concepts from the get go
4. The labs are well-equipped with most major and minor equipment required for Biotechnology. Above all, you can use it all absolutely free if you know how to use it.
5. Following through the above point, you will be taught how to use all these equipment due course and the curriculum encases components which may result in you learning stuff on your own
6. Also you will be encouraged to publish papers and this is a huge learning experience.

Congratulations on your results. The JEE Main Cutoff for 2022 was recently released, and usually this cutoff is of two types: the qualifying cutoff and the admission cutoff. The joint seat allocation authority JoSAA will release the admission cutoff for JEE Main which is the opening and closing ranks for B.Tech admission in each government institute such as NIT. According to the information you have given, you may be able to get into select institutes such as NIT Warangal, Netaji Subhas University of Technology (West Campus), and Indian Institute of Information Technology, Lucknow. However, it will also depend on the branch and your home state. You can also get admission into government colleges in your state that accept JEE scores. Alternatively, you can use the Shiksha platform's JEE Main College Predictor 2022 (https://www.shiksha.com/engineering/jee-main-college-predictor) to get more specific recommendations based on courses, fees, and rank. Here you need to enter your JEE rank or percentile, gender, category, and domicile to get recommendations of possible good colleges.
