CMU Email with option to switch RD to ED

Oh wow, I never heard of this before. My son applied for ED SCS and got deferred to RD. Still waiting. Now curious what did your son decide for ED and outcome of this decision if you don’t mind sharing?Good luck. My son had the option of declaring the second major as part of RD. His argument was very similar no point in doing any other major if it was not for CS.
