Manipal University which is based out in Karnataka is the parent organization of Sikkim Manipal University. Manipal University (MU) is well ahead of Sikkim Manipal University (SMU) in terms of placement quality, infrastructure, faculty, and other factors.
Many people, on the other hand, believe that Sikkim Manipal is the parent organization of Manipal University in Karnataka. Some people have never heard of the Manipal University of Karnataka, but thanks to aggressive marketing, everyone has heard of SMU.
A degree from SMU is worth only half as much as a degree from Manipal University in Karnataka. However, I know some folks who attended SMU and are doing rather well, owing to their abilities rather than the college they chose.
In general, SMU is not a great option for your studies. The remote learning or online MBA program, which is promoted and marketed significantly on television, is not nearly as beneficial as it appears. The quality of students who have pursued an MBA program is not up to par, as they lack a degree of confidence and intelligence. So, if you have other possibilities, I would advise you to not choose SMU as it would not prove to be a wise career choice for you.
