Do I have a good chance of getting into Notre Dame, Hopkins, or any Ivies?

All we really need to know is your unweighted GPA, approximate class rank, SAT/SAT II scores, what you plan to major in, and how you've stood out in that field to impress top schools. None of which you gave here. If it's math and science, the related clubs are a good start, but getting involved in those fields themselves would have been much better. Based on all this, probably a below average shot at those schools.
