Sorry. I didn't get your question properly. But i believe your question is if you can spend one more year preparing to get admission in good college or take admission in average college. I would say that depends on a lot of things. Like what are doing currently. If you working and take one more year you definetly prepare for one more year. Doing MBA from any institute would not fetch much. You need to get ABM degree (Agri based Management) or MBA from good institute. Only then, it would be of use and you can end up having good career. So if you have patience and ability to work hard, I would suggest prepare for one more year and join in a good college.
