If you get deferred, then accepted, by LSA applying for Ross, are you placed into the Regular Decision pile for Ross?
There is no such thing as EA for Ross. After you are accepted to LSA – whether it’s EA or RD – then your application is sent over to Ross. There are endless combinations of different timings. Ross does not necessarily notify applicants in the order in which they receive the applications. You can be admitted to LSA EA, in December, but then not hear from Ross until April. Or You can be deferred to the RD round from LSA, get accepted to LSA in February, and hear from Ross in March. There’s no standard timing.
