When it comes to pursuing a Distance MBA, IGNOU is the safest option. However, there are also alternatives like SCDL (Symbiosis), SMU (Sikkim Manipal), IMT Ghaziabad, etc. Private institutes often face issues regarding their recognition from DEC (Distance Education Council), which has its offices at IGNOU. Nonetheless, many individuals opt for programs at SCDL and other private institutes to enhance their careers.
My personal recommendation would be to err on the side of caution and choose an MBA from IGNOU or any other government university.
