Hey.

The cut off for admission in Manipal Institute of Technology, Manipal for the CSE branch was a rank of 1893 in the previous year. In Sikkim Manipal Institute of Technology the cut off for Computer Science Engineering was a rank of- 41708 and for admission in Manipal University, Jaipur,  the cut off for Computer Science Engineering was a rank of 10867.

Hence you'd require a rank around this range for a fair chance of admission in these respective campuses.

Best of luck
