Hello Aspirant,

It is not possible to give an exact timing because it varies from college to college. It also depends on whether you have taken a regular full time or part time course. . In general for a full time MBA, the timings would be from morning 9 or 10 am to evening 5 or 6 pm.  If it is an executive MBA for professionals then classes will be conducted on an hourly basis during weekends and evenings.

All the best
