Pay for almost 300 USD to submit application in Msc HFE. The program director send me an nomination letter mention that the decision will be made on the end of March. However, until yesterday 4/24 still no update information from program. Now it is 4/25, it only show denied by dept. without any notification and email. This is the worst experience of application in the USA. Although, I've gotten other universities' admission offer(some of their Q.S rank in 100), I still really angry about the administrated efficient and all the thing about this diploma mill.
