StA updated it’s Website removing the statement in “After You Apply” about providing decisions for those who apply by 10/31 by the end of the third week of November, and otherwise within 4 weeks of receipt of your application. Now it just says that admissions decisions will be made on a rolling basis:
"We make decisions on international applications on a rolling basis.
If you are an International applicant who applied through a direct application or the Common Application, you will receive a response to your application by email. This email will outline your offer and conditions from the International Undergraduate team. You should respond to your offer by replying directly to this email, indicating whether or not you will be taking up your place.
If you have any questions relating to your offer, please email the international undergraduate team (myapplication@st-andrews.ac.uk) who will be happy to help you. We recommend that you reply to your offer by 31 May."
