Hello Student,

See, Which branch to choose is entirely depends on your interest regarding that branch, your knowledge about that branch And also depends on for which branch you feel sure about...!!!
So start focusing on that first and then proceed.

Well,both colleges you have mentioned in your question are really good.

Infrastructure is very good at MLRIT and college provides excellent facilities like auditorium,Exclusive placement block equipped with an exclusive Seminar Hall, GD rooms and Interviews panel rooms, and many more.The CSE department Of college has been striving hard to inculcate conceptual and technical skills in students through a scientific teaching methodology based on lectures, case studies, seminars, group discussions, project works, assignments, quiz programs,guest lectures etc.Capgemini,L&T infotech,MINDTREE,HSBC,Infosys,FACE,DXC technology,and many more well reputed companies visiting the campus every year.

CMRK:
The CMR institute of technology in Hyderabad, It is also an autonomous institution.
it has a lush green campus,labs,best library as well as well experienced faculty members.
Top recruiters visit every year at cmrk to hire brilliant and hard working candidates.this
Institution perceives the quality standards of academic performance, student's development, and community empowerment.

So as u said,both the institutions are very good at their place and have their own popularity.
