How do I confirm my shift for My Hindi B Exam Tomorrow

So I had an ER in Hindi In Sem 2 (I am in Sem 4 now) aur kal literally dono shift main same subject code hain and my professor is like, "No Idea" 😭

What do I do ?

I live an hour away from my college so it's not like i can wait until they upload the seating schedule

My course is Bcom(Hons)
