Why is chancing odd?

Answered

There is not enough information that you provided in your question for anyone to give you a reasonable answer as to why. You didn't disclose your ECs, unweighted GPA/WGPA, AP scores, SAT/ACT Scores, SAT II scores, talents, whether you are a legacy, recruited athlete, development candidate, deans' list or what your spike or intellectual vitality is. If you want other college-bound kids to weigh in you'd have to share your info. Otherwise, write to the College Vine folks in a private email with your info and ask them. Most people would agree that getting into Harvard is the hardest because they have a very complicated scoring system, much more rigorous than Stanfords. Since 5% is sort of the current Harvard acceptance rate (4.92%) that's probably more accurate than the Stanford one IMO. The other thing is most freshman HS students do not have very many AP or IB scores or SAT IIs to add to their profiles nor are their ECS national level ECS as a 9th grader so I wouldn't put much weight into any of the chancing results. They are more accurate as you put more data into the profile. Honestly, if you only a freshman have those chancing results already you are 99% ahead of everyone else on here.
