hi,
see most of the college allows bsc in computer science or mathematics or physics related discipline candidates to apply for msc in computer science discipline, before applying to any entrance test you need to check the syllabus, the question structure of previous years, then practice the relevant questions, generally question formed according to UG syllabus, msc in computer science candidates may work for NIELIT, drdo, like research organization, also may work as an professor or lecturer in colleges, many mncs hires computer science professionals in analyst positions. however it also need to choose a institute which has decent placement record.
hope it would help.
