IUSO admission day

Hello,

I have received an invitation to attend IUSO admission day. GPA ~3.5 and OAT scores: BIO:400, CHEM:400, ORGO:400, RC: 370, QR: 370, PHYSICS: 360

I was wondering if these scores matter after being invited to the admissions day? Is everyone on the same level who is invited to a admission day "interview"?

Also, what is the admission day like? Any advice? What are the acceptance rate after attending the admissions day?
