Hii Faiz,

The B.com/BBA/Ba (//B.com/BBA/Ba) eco entrance test conducted by Jamia Milia Islamia Unievrsity has a pretty basic mathematics, logical reasoning and GK- both static and current. You can buy a book by arihant publication and attempt all the question in it. It surely will help you get a good score. Also do some previous year questions papers/sets that'll help you with the pattern and also boost your confidence.

Hope it helps,

Thanks.
