What are my chances

my GPA is somewhere between 3.55 to 3.6, and I’m doing mechanical engineering, and I applied with one missing class which is physics 197, I can’t finish that class period. I got offer from UCI a few days ago, but what are my chances of getting in UCSD seriously??? I heard the school is super strict about not finishing major prerequisite class. But I also heard different things from my college counselor, so anyone know anything about it??
