Hi, I am new to grad cafe as I just found it and am so glad I did! Sorry if i am asking an obvious question but I've been accepted to two programs whose deadlines are in a few days. I am waiting to hear back from 3 more schools, one of them being my top choice. Also, two of the programs stated applicants won't hear back until late April or May. What is normal grad school etiquette...? Is it okay to accept one of these schools as a backup and then decline later?
