First 2 days of University are Rosh Hashanah! Help

I literally don’t know what to do, considering I just finished conversion so this is a new problem. For context I am very observant of Yom Tov and Shabbos, so following the laws are very important to me. I am meeting with my Rabbi to talk about this but I’d still appreciate other opinions, especially if you’ve been in a similar situation.

Right now I’m thinking like I’ll go to services on like actual Rosh Hashana, and then on the second day go to class but still try my best not to do anything forbidden. Obv I’m going to have to email my professors beforehand to let them know, and I plan on reaching out to my school’s jewish society to see if they have advice.
