Could anyone help me clear these doubts? :) 1. Considering that most of the Fall 20 aspirants have deferred, does that mean seats for Fall 21 aspirants would be few? Is there a possibility of increasing the batch size? (For US universities in general) 2. Does the fact that i'm a Electronics & Communication undergraduate affect my chances of getting an admit for Masters in Data Science? ( i have relevant projects, research, internships and courses done in DS) 3. Are there academic pre-requisites stating certain courses which we must have completed in our UG? (especially for a person changing streams from ECE to DS) Thanks a lot for your time!!
