Zoology

Since you are from zoology field you will not find any applications in this stream. MBA in Energy and Environment includes technical knowledge and engineering applications too. If you had a degree of B.Sc in environment science you can apply. Also the companies would find difficult to hire you and provide you a profile due to your different specialization as compared to others in a batch. So I would recommend you to choose another stream which is related to zoology instead of E&E.
