Trust me they don’t even respond to students or take their applications if one is not working with an agent. My agent submitted my documents for evaluation and it was taking a considerable time so I asked about it via email and it was the same fucking reply every time! They would just give me an automated reply with a PDF of approved agents in India. In addition to that you have to have your documents evaluated/approved first before sending an application for admission.You can apply on your own, although it seems to be a pain compared to other colleges as the admission form is just a pdf:
As far as I am aware working with an agent is mandatory unless you want to risk it all and do it on your own
