I hadn’t really thought about CSUs, but I will definitely now. I also definitely thinking of changing JHU to RD; I really don’t know if I’d be a great fit there, even if I get in. LORs I think will be okay, I’m not sure I stand out as an exceptional student and don’t want to make assumptions!!
Thank you for the great advice, and for taking the time to respond to post so thoroughly!! I really appreciate it.
