JEE

With an OBC category rank of 142621 in JEE Mains you might get a seat in following colleges with CSE:
IGDTUW-Indira Gandhi Delhi Technical University for Women
K. J. Somaiya College of Engineering, Vidyavihar, Mumbai
Shri Vile Parle Kelvani Mandal's Dwarkadas J. Sanghvi College of Engineering, Vile Parle, Mumbai
Vishwakarma Government Engineering College

Agnel Charities' for. C. Rodrigues Institute of Technology, Vashi, Navi Mumbai
Bansilal Ramnath Agarawal Charitable Trust's Vishwakarma Institute technology, Bibwewadi, Pune
YMCA University of Science and Technology, Faridabad.

Well, the best colleges through JEE Mains are:-
IIIT Hyderabad- For CS you need to get around 1100 rank in JEE Mains. NIT Trichy-Cutoff for CS-1500
NSUT-Cutoff for COE-1800 (outside Delhi)
NIT Surathkal-Cutoff for CS-2500
NIT Warangal-Cutoff for CS-2000
DTU-Cutoff for COE-3000 (outside Delhi)
NIT Allahabad-Cutoff for CS-4000
IIIT Allahabad-Cutoff for CS-6500
IIIT Bangalore-Cutoff for CS-8500
IIIT Delhi - varies as per IIITD rank
NIT Rourkela-4000
Note:- There is not any significant difference between 3,4 &5. Same is the case for 8th,9th and 10th. Cutoffs are approximate and based on 2019 JoSAA and JAC Counseling. All the cutoffs are given for general category and in case of NITs, they are given for outside state quota. Till 2018 NSUT was known as NSIT.

BIT Mesra is a very good college for engineering but if you are not satisfied with your college then definitely you can attend CSAB counseling. The basic difference is that once JoSAA completes its process of admissions for the Indian Institute of Technologies, National Institute of Technologies and other colleges, the Central Seat Allocation Board CSAB conducts some special rounds (generally 2 rounds) to fill up the vacant seats of National Institute of Technologies, Indian Institutes of Information Technology, and other colleges (not IITs). However, Artificial intelligence and Machine learning branch are very demanding nowadays. Because of the advancement of data technology, machine learning, and robotics. As we SEE everywhere, industries that are already using artificial intelligence and machine learning predominantly include the healthcare system, education system, marketing, retail and commerce companies, and financial services. If you want high pay and more benefits while doing work that transforms the world, a career in artificial intelligence and machine learning is for you. On average, computer Science engineers earn more salaries in comparison to other engineering branch students. I hope this will help you.
