The paper acceptance/rejection notification date of the paper in the previous post was March 25th. I didn't get any email or notification yesterday, but when I opened my email today after the lunch break and noticed that my paper is accepted, I was so excited! So the first thing I did, was to take a screenshot of the email and sent it to my family to share the happiness with them. My advisor was not in her office but I believe she has received the acceptance email.
The conference is AIED 2019 and will take place in Chicago on June 25th. I should read the reviewers' notes and revise the paper by April 8th and register for the main conference.
