The Stanford CDS mentions that only 35% of admitted students submitted class rank, so the clear majority of admits had unknown class rank. I’m not familiar with the school system in the US Virgin Islands, but in typical continental US schools, I doubt that a school with so few students would have a mandatory submitted class rank. However, a 3.0 GPA does not bode well for chance of admission (assuming similar grade distribution to US schools). As aleaiactaest mentioned, almost all admits have higher grades.
