I got 206544 crl in jee mains.can i get seat in CSE OR ME OR CIVIL ENGINEERING?

With such a rank it's tough to get
Actually you can't get cse
It's a core branch
You can opt for management quota
All the best

Sorry to say but the chances of getting CSE are next to impossible as CSE is one of the core branches of engineering hence, their cutoffs are usually very high as compared to other branches however the cutoffs of ME and Civil are low but your ranks is poor even if you get the branches you have to compromise with the your choice of college So I would suggest you to rather prepare for jee main 2019 or to look for some private college and you can also take the josaa counseling to try your luck.
Good luck
