Hy Santosh!!
The diificulty of every course entirely depends on the capability and interest of the person in the field. If you are interested in marketing and are good at convincing people and are very creative, this might be the correct stream for you. So this depends on the choice of the individual what stream he wants to get into in. The determination of the level of difficulty of a course is a very opinionated question.
Hope you understand what I am trying to tell you .
Good luck!!
