There's delays this year across every department and almost every college. I've only really heard from a third of my applications, my friend has heard from 1/8 (in math), and some other chem majors I know have heard from 4/13 and 1/6. Even on this website, you can see people asking in the results page if it's delayed for everyone else too. The answer is yes. Many committees haven't met since the break. I am sure that the people that use this website put enough effort and thought into their applications that we will all have great options within the next few weeks. Good luck to everyone!
