The level of difficulty of a program depends on your passion mostly. If you are passionate about learning then an MA in psychology from IGNOU is not that difficult. You can even work while pursuing a Masters.

Firstly attend all classes and complete all practicals. You will be guided by facilitators throughout. This will help you at the time of examinations. Also, the study material provided by IGNOU is very easy so I don’t think overall it will be a difficult ride.
