MCOM OR MCA SALARY PACKAGE WISE
Both MCA and M.com are Masters course.You can pursue these courses after completing B.com and BCA respectively. Career wise MCA will be a better option because after completing MCA you can have option of working in many IT companies, and since IT companies are booming in India, it will be right career choice. After M.com you will not have many options, you will have to go for preparing government exams or you will have to give NET examination in order to become a teacher, professor etc.
I hope this helps.
