well..i think you should first try the top institutes first like iim's, iift, spjain and all. If you dont get there...try giving entrances for different universities like DU, IP, Jamia, symbiosis. If that does'nt work, then u can try MAT. And if nothing works then you can go to Amity (only if you have lots of money with u).
Otherwise i would say, drop an year, prepare again. There is no harm of taking sometime and preparing properly. Remember, your first step is very important.
