<p>Many of the other UCs are good for math and physics, so consider them in your list as possible matches and safeties.</p>
<p>As advanced as you currently are in math (taking college sophomore level math as a high school junior – three years ahead), you probably want a school with a strong graduate program in math, because you are likely the student who will want to take graduate level math courses and do graduate level research as an undergraduate.</p>
<p>MIT, Stanford, Princeton, and Harvard are among the usual private school suspects for math and physics (but they are all super selective). Minnesota and Stony Brook are worth a look as lower cost and possible safety-level admissions out of state schools good in these subjects, if you feel that the other UCs are not sufficient for this purpose.</p>
<p>Do you have cost constraints?</p>
