B.Tech

The answer vary as the definition of good college depends on you, I know some who are repeating even after getting 4k rank in JEE Advanced. Let's make a list of good options ( in my opinion)
Creamy layer (CSE, ECE, electrical, mechanical)
NIT Trichy
NIT Warangal
NIT Surathkal
Better NITs ( CSE, ECE, electrical)
NIT Allahabad ( chemical is also famous branch of Allahabad because of its location near chemical industries of Uttar Pradesh)
NIT Rourkela
NIT Jaipur
NIT Calicut
NIT Nagpur
Other good NITs ( only CSE and ECE)
NIT Bhopal
NIT Surat
NIT Jamshedpur ( mechanical is a good option because of location)
NIT kurukshetra, Jalandhar, durgapur, Hamirpur, Delhi
NIT Patna
Other NITs
Okay, now let's discuss the cutoff :- ( all cut-offs are for other state)
Creamy layer (upto mechanical)
General = 9900 Marks= 175
OBC NCL =3300 Marks= 154
Better NITs ( upto electrical)
General= 12500 Marks=155+
OBC NCL= 3900 Marks 142
Other good NITs ( upto ECE)
General=20000 Marks= 141
OBC NCL=6000 Marks=134+
Here the marks mentioned are approximated using the last two JEE Main sessions ( Jan and September 2020). The marks required for EWS and OBC candidates are almost parallel for all india quota so one can get the idea for EWS.

Hi. As you might be knowing that BIET is the first institute in India to introduce a new BTech program on AI engineering. Though the seats are very limited and the name AI is having such a demand now a days, the cutoff rank for it will be competing with that of CSE of IITH and other old IITs.
My view upon the branch is that it will be having some awesome faculty . Firstly we at IITH are having some really good profs in this field . I have taken a course Intro to AI and ML in this sem .The course provided us a quick start to understand what AI is all about. It was really awesome. So if you are truly intrested in pursuing a degree in AI , there's no other fantastic place other an BIET.
FEEL FREE TO UPVOTE , So that many aspirants will be knowing about the new branch.
So it's the first round
My predictions are infact true

It depends on perspective of every individual, I would like to share my perspective.
Civil is a good branch, you have so many interesting subjects to learn, many people choose to avoid giving civil a preference 'cause they think Civil me placement nahi hota' 'Construction site par kaam karna padega .But civil has so many sub branches (Structural, Environmental, Transportation, Water Resources, Construction technology, etc) which gives a good opportunity for further studies.
I agree that the placement scenario of civil is poor if you compare it to Mech, CSE, ECE, EEE , but if you are good with your subjects it shouldn't be a problem.
Most of the profs in VNIT are good, but some are literally unbearable xD, however overall you'll have a good experience.
