I referred to the website you have mentioned. They have nowhere mentioned on the website that CS is an eligible degree for the NET SET Exam.
About PhD, CS/CA/ICWA are all eligible as a post graduate courses for PhD, this is true but for NET SET I am not aware of any such provision.
I KINDLY REQUEST YOU TO SEARCH ON THE WEBSITE www.aiuweb.org AND IF YOU GET A LINK THEN SEND ME HERE.
THANKS IN ANTICIPATION.
