Hi,

The eligibility criteria for msc. Chemistry of Banasthali university says that you need to score 60%  in BSc. with Chemistry. This means that in the total duration of 3 year undergraduate course you will need to obtain 60% marks. For example you got 50% in 1St year, 75% in 2nd year and 55% in 3rd year. So in aggregate you got 60% marks(50%+75%+55%/3=60%)
