Chance Website Confusion

According to Cappex, my son has a low to medium chance of admission to Bowdoin and a Medium to High chance at Princeton, Vanderbilt and University of Chicago?

This makes no sense to me since Bowdoin is not as selective than the others? Are chance websites garbage?

For schools that admit less than 10% of their applicants, yes, chance sites are garbage. However, they can sometimes help filter out some overreaches on some students’ college lists.

Having the same issue. If their ACT score are competitive and their GPA’s are high they pretty much qualify for all the schools…BUT then there are the % of admits that make it so hard to figure.

Looking for a way to figure out good safeties, but being a homeschooler it’s nerve racking because you really don’t know how the adcomm will feel about that.
