Dear applicant it's good that you are dropping a year to take another chance and make it next time. Now if you think of a Back-up course and if it is B.Sc Agriculture then it's a very good one. Now-a-days Agriculture Course is an Exponentially Growing course, offering you vast career opportunities that may be Agricultural Officer, Agricultural Inspector, Manager and many more. You will receive good jobs offering you hefty sum of salaries.

Hope it helps!!

Good luck!!
