Your explanation is also plausible. Best of Luck with your application.
I went through previous year's (or probably 2020) thread, decision is likely to be announced around Mid march.... like acceptances were received around 13th to 14th and rejections followed round 17th.
They have clearly written on their website that letter of recommendation from supervisor is a must provided that candidate has a postgraduate. Asking for reference letter from undergrad is odd but maybe it means that they do not want to reject you and have asked for the letter .... big maybe though!!!
Greetings!
Only 10 days have elapsed and anxiety of waiting for decision is at its peak....So, if anyone is in the same boat, let us use this thread to know application status and other queries related to funding sources .....
