Is Sikkim Manipal University good for pursuing MBA through distance education?

Yes, SMU is very good, the curriculum is very lucid to understand and it has good brand recognition. Other reputed colleges include NMIMS, Welingkar, Symbiosis, Amity and IGNOU.

Amity, ICFAI and IGNOU are better than SMU by a far margin. The SMU is the worst University to pursue any course now. Even their recognition was revoked but later reinstated.
