“The Dean” does not do admission “chances” and, even if I did, it’s way too early to assess yours. What I can tell you, however, is what Ivy admission officials often seek in their accepted applicants:
-Top grades in the most rigorous courses. Accepted Ivy candidates may even take classes at local colleges or over the summer after completing the most demanding courses at their own high schools and still seeking more challenge. If your transcript shows a special passion for some particular academic area, so much the better.
