Dear candidate although JNTU self finance B.Tech plus M.Tech course is a good one, but I would suggest you not to go for any hybrid courses, rather focus differently on your Bachelor's and Masters degree. Out of that CVR college of Engineering is indeed a good one, their infrastructure and top notch faculties will give you a huge support. The Placements for ECE branch starts with package of 4-6 LPA.
