Do you think I have a good chance of getting into Harvard College?

Apply to Harvard, and Pomona, and Duke, and Williams; but keep in mind that your odds are, AT BEST, 3-5%. So, apply to a couple universities/LACs in the top 25, and a few more in the top 40, and a few more in the top 75.
Did I miss it, or did you not indicate what your parents’ budget is?
