Amity business school is not definitely a top b-school, bust yes it is much better than many b-schools in the country. If you have the better option than its OK otherwise Amity is not a bad choice. It is one of the costliest MBA in the country and in the recent past they got very bad publicity which really affected its image. Moreover the management of ABS doesnt seems to be serious for improving the quality of its faculty. They are spending huge amount of money in ads but the same money can be spent in attracting much better faculty and improving the library and other infrastructure. (Although building is good but academic infrastructure is poor). Campus placements are there but of low quality.
